Specifically it limits the queue size for a tty to 64K characters (128Kbytes) worst case even if the tty is ignoring tty->throttle.

Make this top cpus file read-only. On systems that have cpusets configured in their kernel, but that aren't actively using cpusets (for some distros, this covers the majority of systems) all tasks end up in the top cpuset. If that system does support CPU hotplug, then these tasks cannot make use of CPUs that are added after system boot, because the CPUs are not allowed in the top cpuset. This is a surprising regression over earlier kernels that didn't have cpusets enabled. In order to keep the behaviour of cpusets consistent between systems actively making use of them and systems not using them, this patch changes the behaviour of the 'cpus' file in the top (root) cpuset, making it read only, and making it automatically track the value of cpu_online_map. Thus tasks in the top cpuset will have automatic use of hot plugged CPUs allowed by their cpuset.

If we - shut down a clean array, - restart with one (or more) drive(s) missing - make some changes - pause, so that they array gets marked 'clean', the event count on the superblock of included drives will be the same as that of the removed drives. So adding the removed drive back in will cause it to be included with no resync. To avoid this, we only update the eventcount backwards when the array is not degraded. In this case there can (should) be no non-connected drives that we can get confused with, and this is the particular case where updating-backwards is valuable.

This is wrong behaviour, fragment may be NOT allocated, but mapped, this happened because of "block map" function not checked allocated fragment or not, it just take address of the first fragment in the block, add offset of fragment and return result, this is correct behaviour in almost all situation except call from ufs_truncate. 2) Almost all implementation of UFS, which I can investigate have such "defect": if you have full disk, and try truncate file, for example 3GB to 2MB, and have hole in this region, truncate return -ENOSPC. I tried evade from this problem, but "block allocation" algorithm is tied to right value of i_lastfrag, and fix of this corner case may slow down of ordinaries scenarios, so this patch makes behavior of "truncate" operations similar to what other UFS implementations do.

This happened because of "goal" is calculated in wrong way in block allocation path, as I see this problem exists also in 2.4.

On an nForce4-equipped machine with two SATA disk in raid1 setup using dmraid, we experienced frequent deadlock of the system under high i/o load. 'cat /dev/zero > ~/zero' was the most reliable way to reproduce them: Randomly after a few GB, 'cp' would be left in 'D' state along with kjournald and kmirrord. The functions cp and kjournald were blocked in did vary, but kmirrord's wchan always pointed to 'mempool_alloc()'. We've seen this pattern on 2.6.15 and 2.6.17 kernels. http://lkml.org/lkml/2005/4/20/142 indicates that this problem has been around even before. So much for the facts, here's my interpretation: mempool_alloc() first tries to atomically allocate the requested memory, or falls back to hand out preallocated chunks from the mempool. If both fail, it puts the calling process (kmirrord in this case) on a private waitqueue until somebody refills the pool. Where the only 'somebody' is kmirrord itself, so we have a deadlock. I worked around this problem by falling back to a (blocking) kmalloc when before kmirrord would have ended up on the waitqueue. This defeats part of the benefits of using the mempool, but at least keeps the system running. And it could be done with a two-line change. Note that mempool_alloc() clears the GFP_NOIO flag internally, and only uses it to decide whether to wait or return an error if immediate allocation fails, so the attached patch doesn't change behaviour in the non-deadlocking case. Path is against current git (2.6.18-rc4), but should apply to earlier versions as well. I've tested on 2.6.15, where this patch makes the difference between random lockup and a stable system.

CCID3 is meant to alter sending rate based on RTT and loss. The performance was verified against: http://wand.net.nz/~perry/max_download.php For example I tested with netem and had the following parameters: Delayed Acks 1, MSS 256 bytes, RTT 105 ms, packet loss 5%. This gives a theoretical speed of 71.9 Kbits/s. I measured across three runs with this patch set and got 70.1 Kbits/s. Without this patchset the average was 232 Kbits/s which means Linux can't be used for CCID3 research properly. I also tested with netem turned off so box just acting as router with 1.2 msec RTT. The performance with this is the same with or without the patch at around 30 Mbit/s. Signed off by: Ian McDonald Signed-off-by: David S.

Without this our special test settings could remain seriously confusing the system BIOS's setup menu. Both are very much related and are must haves, to avoid messing up the uguru CMOS settings. Detailed changes: - Much improved timeout / wait for status handling. Many thanks to Sunil Kumar, for all his testing, ideas and patches! The code now first busy waits, polling the uguru for the expected status as this usually succeeds pretty quickly (within 90 reads). To avoid unnecessary CPU burn in timeout conditions, the amount of busy waiting has been halved from previous versions (120 tries instead of 250). This is not a problem, because this version goes to sleep after 120 attemps for 1 jiffy and then tries again, it does this sleep and try again 5 times before finally giving up. This (almost?) completly removes the timeout errors some people have seen regulary. Apparently some older uguru versions sometimes are distracted for a (relatively) long time. This solves this. - These timeout errors not only occur in the sending address part of reading the uguru but also in the wait for read state, so errors in this state are now handled as retryable just like send address state errors and are only logged and reported to userspace if 3 executive tries fail. - Fix a very nasty bug in the bank1 sensor type detection code, where it would not restore the original settings in any of the error paths! - Since not successfully restoring the original settings can seriously confuse the system BIOS (hang when entering the relevant setup menu), we now try restoring them 3 times before giving up.

A typical mkdir(2) calls two inode_operations: lookup and mkdir. The lookup operation would fail with ENOENT in common case. I think it is unnecessary because the subsequent mkdir operation can check it. In case of creat(2), lookup operation is called with the LOOKUP_CREATE flag, so individual filesystem can omit real lookup. e.g. nfs_lookup(). Here is a sample patch which uses LOOKUP_CREATE and O_EXCL on mkdir, symlink and mknod. This uses the gadget for creat(2). And here is the result of a benchmark on NFSv3. mkdir(2) 10,000 times: original 50.5 sec patched 29.0 sec Signed-off-by: ASANO Masahiro Signed-off-by: Andrew Morton Signed-off-by: Trond Myklebust (cherry picked from fab7bf44449b29f9d5572a5dd8adcf7c91d5bf0f commit) commit ddeff520f02b92128132c282c350fa72afffb84a Author: Nikita Danilov Date: Wed Aug 9 13:53:47 2006 -0400 NFS: Fix a potential deadlock in nfs_release_page nfs_wb_page() waits on request completion and, as a result, is not safe to be called from nfs_release_page() invoked by VM scanner as part of GFP_NOFS allocation.

Analysis shows that these problems are caused by bogus PCS values from those controllers. Before the PCS update, the driver didn't honor PCS regs exactly and probed them in many cases PCS reports no device. Now that PCS is honored exactly, these hardware problems are visible. This patch makes ICH5 ignore PCS.

Alright, this one is only triggered when slab debugging is enabled. The slabs are assumed to be aligned on a HUGEPTE_TABLE_SIZE boundary. The free path makes use of this assumption and uses the lowest nibble to pass around an index into an array of kmem_cache pointers. With slab debugging turned on, the slab is still aligned, but the "working" object pointer is not. This would break the assumption above that a full nibble is available for the PGF_CACHENUM_MASK. The following patch reduces PGF_CACHENUM_MASK to cover only the two least significant bits, which is enough to cover the current number of 4 pgtable cache types. Then use this constant to mask out the appropriate part of the huge pte pointer.

This fixes yet another sunsab problem, when console is set to anything but the first port. The console framework calls sunsab_console_setup for each port, and we end up setting up a console on a not yet discovered port, which leads to an Oops. Instead, defer console setup until the requested port is properly initialized. Tested on an E250 through an RSC console. Reported by Daniel Smolik Signed-off-by: Marc Zyngier Signed-off-by: David S.
