[PATCH] loop.c cleanups # # This does the following: # - remove trailing spaces # - make loop.h independent by including bio.h, blk.h, spinlock.h # - replace the lock/unlock functions by module_get/module_put; # in struct loop this is the change # - void (*lock)(struct loop_device *); # - void (*unlock)(struct loop_device *); # + struct module *owner; # - replace the integer lo_encrypt_type by the pointer lo_encryption; # there was a race with loop_unregister_transfer # - fixed an off-by-one in loop_register_transfer # # This is Step 1 of a series of half a dozen or so. # # Half of the above is from Jari.

I believe it's wisest to roll these both together # into this one patch since they both deal with making NBD work better # with the 2.5 linux block layer design and without either of which, it's # possible that NBD will corrupt memory. # # Other changes I'd like to see introduced (like in the earlier jumbo # patch) meanwhile are feature enhancements so they can wait. This patch # also should address all the very helpful concerns that have been raised # so far. Particularly: # # 1. that the very first submitted NBD patch was broken down [Andrew] # 2. that only 1 spinlock is used for all the NBD request_queue structures # used [Jens,Al] # 3. that kmap() is used in case of highmem pages [Jens] # 4. that the allocation of request_queue is dynamic and seperate from # other allocated objects [Al] # -------------------------------------------- # 03/06/22 davem@nuts.ninka.net 1.1310.60.1 # [SPARC64]: Update struct compat_statfs. # -------------------------------------------- # 03/06/22 davem@nuts.ninka.net 1.1310.60.2 # [SPARC64]: Update solaris compat layer for vfs_statfs() changes. # -------------------------------------------- # 03/06/22 davem@nuts.ninka.net 1.1310.60.3 # [SPARC]: Update for show_stack() changes. # -------------------------------------------- # 03/06/22 davem@nuts.ninka.net 1.1310.60.4 # [SPARC]: Add {f,}statfs64 syscall entries. # -------------------------------------------- # 03/06/22 davem@kernel.bkbits.net 1.1310.59.4 # Merge davem@nuts.ninka.net:/home/davem/src/BK/sparc-2.5 # into kernel.bkbits.net:/home/davem/sparc-2.5 # -------------------------------------------- # 03/06/22 rusty@rustcorp.com.au 1.1310.59.5 # [PATCH] Workqueue Exit Neatening # # Jeff Garzik points out the initializing the exit completion at # exit time is foolish: we should just initialize it at creation time # live everything else in that structure, and avoid the memory barrier. # -------------------------------------------- # 03/06/23 rmk@flint.arm.linux.org.uk 1.1310.43.26 # [PCMCIA] Fix ide-cs driver name (for PCMCIA binding) # # Problem noticed by Eivind Tagseth. # # We seem to have resurected the "ide_cs" driver name for the ide-cs module. # Restore the driver name to "ide-cs". # -------------------------------------------- # 03/06/23 dwmw2@infradead.org 1.1310.59.6 # MTD driver cleanups... # # - Fix AFS partitioning oops when no partitions are found # - Add missing spin_unlock, optimise buffer writes in Intel NOR driver # - Fix DiskOnChip Millennium Plus register OutputControl register definition # - Fix DiskOnChip drivers to indicate correct ECC type # - Fix map drivers to use ARRAY_SIZE instead of redefining it. # - Make uCLinux map driver depend on !MMU # - Fix NAND write verify problem on some chips # - Other trivia from Rusty. # -------------------------------------------- # 03/06/23 dwmw2@infradead.org 1.1310.59.7 # Replace mtd_blktrans ->ioctl() method with ->getgeo() and ->flush() # # ... and also fix the embarrassing bug where NFTL and INFTL will # barf and exit if the add_mtd_blktrans_dev() function _exists_, # rather than actually calling it and barfing if it returns non-zero :) # -------------------------------------------- # 03/06/23 dwmw2@infradead.org 1.1310.59.8 # Trivia: use JFFS2 PAD() macro instead of masking manually. # -------------------------------------------- # 03/06/23 dwmw2@infradead.org 1.1310.59.9 # Fix jffs2_statfs w.r.t. statfs64 # -------------------------------------------- # 03/06/23 dwmw2@infradead.org 1.1310.59.10 # Remove superfluous debugging in mtd_blkdevs.c # -------------------------------------------- # 03/06/23 jgrimm@touki.austin.ibm.com 1.1305.18.1 # Merge touki.austin.ibm.com:/home/jgrimm/bk/linux-2.5 # into touki.austin.ibm.com:/home/jgrimm/bk/lksctp-2.5.work # -------------------------------------------- # 03/06/24 anton@samba.org 1.1315.1.2 # Merge samba.org:/scratch/anton/linux-2.5 # into samba.org:/scratch/anton/tmp3 # -------------------------------------------- # 03/06/24 anton@samba.org 1.1318 # Merge bk://ppc.bkbits.net/for-linus-ppc64 # into samba.org:/scratch/anton/tmp3 # -------------------------------------------- # 03/06/23 greg@kroah.com 1.1310.61.1 # Merge kroah.com:/home/greg/linux/BK/bleed-2.5 # into kroah.com:/home/greg/linux/BK/gregkh-2.5 # -------------------------------------------- # 03/06/23 ink@jurassic.park.msu.ru 1.1310.62.1 # [PATCH] PCI: fix non-hotplug build # # Current BK won't build when CONFIG_HOTPLUG is not set due to # undefined references to pci_destroy_dev in hotplug.c. # I think it makes sense to not compile hotplug.c in this case at all. # Also, this allows to get rid of several function which are unused # in non-hotplug kernel. # # Tested on Alpha. # -------------------------------------------- # 03/06/23 ink@jurassic.park.msu.ru 1.1310.62.2 # [PATCH] PCI: fix alpha for reimplement pci proc name # # On Fri, Jun 20, 2003 at 02:24:13PM -0700, Greg KH wrote: # > Thanks, I've reverted your previous patch, and fixed the one typo in # > this patch and applied it all to my bk tree.

Most of the most recent ones are due to some # newer Intel chipsets (865, 875). # # The IO APIC Version register doesn't indicate the differences in these # IO APICs. # # I have an patch that addresses these chipsets. It has been tested by a # few people with good results and has been blessed by Maciej Rozycki. # # Other than conditionally decoding IO APIC registers 2 and 3, we could # alternately ignore them since Linux doesn't use the values for anything # other than printing them. # # This patch ignores IO APIC register 2 if it's the same value as IO APIC # register 1. It also reads IO APIC register 3 if the IO APIC version is # >= 0x20, but some chipsets don't support this register, so it is also # ignored if its value if the same as IO APIC register 1 or 2. # # Another possible(?) alternative is to read the PID/VID of the device to # determine which registers it supports. However, PCI devices have not # been scanned at this point in init, so it would require scanning PCI # config space directly and I don't yet see the point of doing that. # # Oh, and the UNEXPECTED_IO_APIC() function doesn't print anything in # 2.5.current and I didn't change that. # -------------------------------------------- # 03/06/24 daniel.ritz@gmx.ch 1.1310.1.133 # [PATCH] alloc_etherdev for 3c574_cs # # net_device is no longer allocated as part of the driver's private structure, # instead it's allocated via alloc_netdev. compile tested only since no hardware # against 2.5.73-bk # # # -daniel # # # ===== drivers/net/pcmcia/3c574_cs.c 1.17 vs edited ===== # -------------------------------------------- # 03/06/24 daniel.ritz@gmx.ch 1.1310.1.134 # [PATCH] alloc_etherdev for 3c589_cs # # net_device is no longer allocated as part of the driver's private structure, # instead it's allocated via alloc_netdev. compile tested only since no hardware # against 2.5.73-bk # # # -daniel # # ===== drivers/net/pcmcia/3c589_cs.c 1.17 vs edited ===== # -------------------------------------------- # 03/06/24 daniel.ritz@gmx.ch 1.1310.1.135 # [PATCH] alloc_etherdev for fmvj18x_cs # # net_device is no longer allocated as part of the driver's private structure, # instead it's allocated via alloc_netdev. compile tested only since no hardware # against 2.5.73-bk # # # -daniel # # ===== fmvj18x_cs.c 1.21 vs edited ===== # -------------------------------------------- # 03/06/24 daniel.ritz@gmx.ch 1.1310.1.136 # [PATCH] alloc_etherdev for nmclan_cs # # net_device is no longer allocated as part of the driver's private structure, # instead it's allocated via alloc_netdev. compile tested only since no hardware # against 2.5.73-bk # # # -daniel # # ===== nmclan_cs.c 1.14 vs edited ===== # -------------------------------------------- # 03/06/24 daniel.ritz@gmx.ch 1.1310.1.137 # [PATCH] alloc_etherdev for smc91c92_cs # # net_device is no longer allocated as part of the driver's private structure, # instead it's allocated via alloc_netdev. compile tested only since no hardware # against 2.5.73-bk # # # -daniel # # ===== smc91c92_cs.c 1.18 vs edited ===== # -------------------------------------------- # 03/06/24 scott.feldman@intel.com 1.1310.1.138 # [PATCH] Remove CAP_NET_ADMIN check for SIOCETHTOOL's # # dev_ioctl already checks capable(CAP_NET_ADMIN), so no need to do so in # drivers. # -------------------------------------------- # 03/06/24 shemminger@osdl.org 1.1310.1.139 # [PATCH] 2.5.70 - eepro100 - use alloc_etherdev # # Ignore earlier patch -- this one locks and free's as appropriate. # Tested on 2.5.72 with SMP. # # Of course, it begs the question why have two (now three) versions of drivers for # the same hardware... # -------------------------------------------- # 03/06/24 davem@nuts.ninka.net 1.1310.78.1 # [USB]: Use linux/dma-mapping.h not asm/dma-mapping.h in kaweth.c # -------------------------------------------- # 03/06/24 davem@nuts.ninka.net 1.1310.78.2 # [PCI]: Export pci_enable_device_bars to modules. # -------------------------------------------- # 03/06/24 davem@nuts.ninka.net 1.1310.78.3 # [SPARC64]: Update defconfig. # -------------------------------------------- # 03/06/24 davem@nuts.ninka.net 1.1310.78.4 # [SERIAL]: Sanitize sparc serial console configuration. # -------------------------------------------- # 03/06/24 davem@nuts.ninka.net 1.1310.78.5 # [SPARC64]: Update defconfig. # -------------------------------------------- # 03/06/25 anton@samba.org 1.1326 # Merge samba.org:/scratch/anton/linux-2.5 # into samba.org:/scratch/anton/tmp3 # -------------------------------------------- # 03/06/25 paulus@samba.org 1.1310.58.8 # PPC32: remove check for ERESTARTNOHAND in syscall return path. # # This error is handled in the signal delivery code and should never be # returned from a syscall unless a signal is pending.

More importantly, the current organization of the code has a # serious problem. The SCSI core does not modify the host driver when the # reference count for either shost->class_dev or shost->host_gendev drops to # 0.

Without this, load balance across nodes of dissimilar cpu # counts can cause unfairness and sometimes lower overall performance. # # For example, a 2 node system with 4 cpus in the first node and 2 cpus in # the second. A workload with 6 running tasks would have 3 tasks running on # one node and 3 on the other, leaving one cpu idle in the first node and two # tasks sharing a cpu in the second node. The patch would ensure that 4 # tasks run in the first node and 2 in the second. # # I ran some kernel compiles comparing this patch on a 2 node 4 cpu/2 cpu # system to show the benefits. Without the patch I got 140 second elapsed # time. With the patch I get 132 seconds (6% better). # # Although it is not very common to have nodes with dissimilar cpu counts, it # is already happening.

Passive initialization model ============================ -LLD initialization (both built-in and module) and shutdown are "wired -up" by passing function pointers to the module_init() and module_exit() -macros respectively. In this model the function identified by "module_init" -must call scsi_register_host() and the function identified by "module_exit" -must call scsi_unregister_host(). -Most LLDs inherited from the lk 2.4 series include a file called -"scsi_module.c" [yes the ".c" is a little surprising] in their -source code. For that file to work a declaration like this is needed before -it is included: - static struct SHT driver_template = DRIVER_TEMPLATE; +These older LLDs include a file called "scsi_module.c" [yes the ".c" is a +little surprising] in their source code. For that file to work an +instance of struct scsi_host_template with the name "driver_template" +needs to be defined. Here is a typical code sequence used in this model: + static struct scsi_host_template driver_template = { + ... + }; #include "scsi_module.c" -In this case "DRIVER_TEMPLATE" is defined to be a structure initializer -that is placed in the driver header file by convention. It contains -pointers to supported interface functions and other values. +The scsi_module.c file contains two functions: + - init_this_scsi_driver() which is executed when the LLD is + initialized (i.e. boot time or module load time) + - exit_this_scsi_driver() which is executed when the LLD is shut + down (i.e. module unload time) +Note: since these functions are tagged with __init and __exit qualifiers +a LLD should not call them explicitly (since the kernel does that). Here is an example of an initialization sequence when two hosts are detected (so detect() returns 2) and the SCSI bus scan on each host finds 1 SCSI device (and a second device does not respond).

It may be possible to write a LLD +that uses both initialization models. + + +Reference Counting +================== +The Scsi_Host structure has had reference counting infrastructure added. +This effectively spreads the ownership of struct Scsi_Host instances +across the various SCSI layers which use them. Previously such instances +were exclusively owned by the mid level. LLDs would not usually need to +directly manipulate these reference counts but there may be some cases +where they do. + +There are 3 reference counting functions of interest associated with +struct Scsi_Host: + - scsi_host_alloc(): returns a pointer to new instance of struct + Scsi_Host which has its reference count ^^ set to 1 + - scsi_host_get(): adds 1 to the reference count of the given instance + - scsi_host_put(): decrements 1 from the reference count of the given + instance.
