Subsequent calls to this without first thawing the fs may return -EBUSY. **who** should be: * ``FREEZE_HOLDER_USERSPACE`` if userspace wants to freeze the fs; * ``FREEZE_HOLDER_KERNEL`` if the kernel wants to freeze the fs. * ``FREEZE_MAY_NEST`` whether nesting freeze and thaw requests is allowed. The **who** argument distinguishes between the kernel and userspace trying to freeze the filesystem. Although there cannot be multiple kernel freezes or multiple userspace freezes in effect at any given time, the kernel and userspace can both hold a filesystem frozen. The filesystem remains frozen until there are no kernel or userspace freezes in effect. A filesystem may hold multiple devices and thus a filesystems may be frozen through the block layer via multiple block devices. In this case the request is marked as being allowed to nest by passing FREEZE_MAY_NEST. The filesystem remains frozen until all block devices are unfrozen. If multiple freezes are attempted without FREEZE_MAY_NEST -EBUSY will be returned. During this function, sb->s_writers.frozen goes through these values: SB_UNFROZEN: File system is normal, all writes progress as usual. SB_FREEZE_WRITE: The file system is in the process of being frozen. New writes should be blocked, though page faults are still allowed. We wait for all writes to complete and then proceed to the next stage. SB_FREEZE_PAGEFAULT: Freezing continues. Now also page faults are blocked but internal fs threads can still modify the filesystem (although they should not dirty new pages or inodes), writeback can run etc. After waiting for all running page faults we sync the filesystem which will clean all dirty pages and inodes (no new dirty pages or inodes can be created when sync is running). SB_FREEZE_FS: The file system is frozen. Now all internal sources of fs modification are blocked (e.g. XFS preallocation truncation on inode reclaim). This is usually implemented by blocking new transactions for filesystems that have them and need this additional guard. After all internal writers are finished we call ->freeze_fs() to finish filesystem freezing. Then we transition to SB_FREEZE_COMPLETE state. This state is mostly auxiliary for filesystems to verify they do not modify frozen fs. sb->s_writers.frozen is protected by sb->s_umount. **Return** If the freeze was successful zero is returned.

If the filesystem defines a private ->lock() method, then **conf** will be left unchanged; so a caller that cares should initialize it to some acceptable default. To avoid blocking kernel daemons, such as lockd, that need to acquire POSIX locks, the ->lock() interface may return asynchronously, before the lock has been granted or denied by the underlying filesystem, if (and only if) lm_grant is set. Additionally FOP_ASYNC_LOCK in file_operations fop_flags need to be set. Callers expecting ->lock() to return asynchronously will only use F_SETLK, not F_SETLKW; they will set FL_SLEEP if (and only if) the request is for a blocking lock. When ->lock() does return asynchronously, it must return FILE_LOCK_DEFERRED, and call ->lm_grant() when the lock request completes. If the request is for non-blocking lock the file system should return FILE_LOCK_DEFERRED then try to get the lock and call the callback routine with the result. If the request timed out the callback routine will return a nonzero return code and the file system should release the lock. The file system is also responsible to keep a corresponding posix lock when it grants a lock so the VFS can find out which locks are locally held and do the correct lock cleanup when required. The underlying filesystem must not drop the kernel lock or call ->lm_grant() before returning to the caller with a FILE_LOCK_DEFERRED return code.h](h)}(h**Parameters**h]j)}(hj=h]h Parameters}(hj=hhhNhNubah}(h]h ]h"]h$]h&]uh1jhj<ubah}(h]h ]h"]h$]h&]uh1hhR/var/lib/git/docbuild/linux/Documentation/filesystems/api-summary:44: ./fs/locks.chM hj<ubj)}(hhh](j)}(h4``struct file *filp`` The file to apply the lock to h](j)}(h``struct file *filp``h]j)}(hj =h]hstruct file *filp}(hj"=hhhNhNubah}(h]h ]h"]h$]h&]uh1jhj=ubah}(h]h ]h"]h$]h&]uh1jhR/var/lib/git/docbuild/linux/Documentation/filesystems/api-summary:44: ./fs/locks.chM hj=ubj)}(hhh]h)}(hThe file to apply the lock toh]hThe file to apply the lock to}(hj9=hhhNhNubah}(h]h ]h"]h$]h&]uh1hhj5=hM hj6=ubah}(h]h ]h"]h$]h&]uh1jhj=ubeh}(h]h ]h"]h$]h&]uh1jhj5=hM hj=ubj)}(hH``unsigned int cmd`` type of locking operation (F_SETLK, F_GETLK, etc.) h](j)}(h``unsigned int cmd``h]j)}(hjY=h]hunsigned int cmd}(hj[=hhhNhNubah}(h]h ]h"]h$]h&]uh1jhjW=ubah}(h]h ]h"]h$]h&]uh1jhR/var/lib/git/docbuild/linux/Documentation/filesystems/api-summary:44: ./fs/locks.chM hjS=ubj)}(hhh]h)}(h2type of locking operation (F_SETLK, F_GETLK, etc.)h]h2type of locking operation (F_SETLK, F_GETLK, etc.)}(hjr=hhhNhNubah}(h]h ]h"]h$]h&]uh1hhjn=hM hjo=ubah}(h]h ]h"]h$]h&]uh1jhjS=ubeh}(h]h ]h"]h$]h&]uh1jhjn=hM hj=ubj)}(h0``struct file_lock *fl`` The lock to be applied h](j)}(h``struct file_lock *fl``h]j)}(hj=h]hstruct file_lock *fl}(hj=hhhNhNubah}(h]h ]h"]h$]h&]uh1jhj=ubah}(h]h ]h"]h$]h&]uh1jhR/var/lib/git/docbuild/linux/Documentation/filesystems/api-summary:44: ./fs/locks.chM hj=ubj)}(hhh]h)}(hThe lock to be appliedh]hThe lock to be applied}(hj=hhhNhNubah}(h]h ]h"]h$]h&]uh1hhj=hM hj=ubah}(h]h ]h"]h$]h&]uh1jhj=ubeh}(h]h ]h"]h$]h&]uh1jhj=hM hj=ubj)}(hU``struct file_lock *conf`` Place to return a copy of the conflicting lock, if found. h](j)}(h``struct file_lock *conf``h]j)}(hj=h]hstruct file_lock *conf}(hj=hhhNhNubah}(h]h ]h"]h$]h&]uh1jhj=ubah}(h]h ]h"]h$]h&]uh1jhR/var/lib/git/docbuild/linux/Documentation/filesystems/api-summary:44: ./fs/locks.chM hj=ubj)}(hhh]h)}(h9Place to return a copy of the conflicting lock, if found.h]h9Place to return a copy of the conflicting lock, if found.}(hj=hhhNhNubah}(h]h ]h"]h$]h&]uh1hhj=hM hj=ubah}(h]h ]h"]h$]h&]uh1jhj=ubeh}(h]h ]h"]h$]h&]uh1jhj=hM hj=ubeh}(h]h ]h"]h$]h&]uh1jhj<ubh)}(h**Description**h]j)}(hj>h]h Description}(hj>hhhNhNubah}(h]h ]h"]h$]h&]uh1jhj>ubah}(h]h ]h"]h$]h&]uh1hhR/var/lib/git/docbuild/linux/Documentation/filesystems/api-summary:44: ./fs/locks.chM hj<ubh)}(hZA caller that doesn't care about the conflicting lock may pass NULL as the final argument.h]h\A caller that doesn’t care about the conflicting lock may pass NULL as the final argument.}(hj>hhhNhNubah}(h]h ]h"]h$]h&]uh1hhR/var/lib/git/docbuild/linux/Documentation/filesystems/api-summary:44: ./fs/locks.chM hj<ubh)}(hIf the filesystem defines a private ->lock() method, then **conf** will be left unchanged; so a caller that cares should initialize it to some acceptable default.h](h:If the filesystem defines a private ->lock() method, then }(hj+>hhhNhNubj)}(h**conf**h]hconf}(hj3>hhhNhNubah}(h]h ]h"]h$]h&]uh1jhj+>ubh` will be left unchanged; so a caller that cares should initialize it to some acceptable default.}(hj+>hhhNhNubeh}(h]h ]h"]h$]h&]uh1hhR/var/lib/git/docbuild/linux/Documentation/filesystems/api-summary:44: ./fs/locks.chM hj<ubh)}(hX8To avoid blocking kernel daemons, such as lockd, that need to acquire POSIX locks, the ->lock() interface may return asynchronously, before the lock has been granted or denied by the underlying filesystem, if (and only if) lm_grant is set.

The file system is also responsible to keep a corresponding posix lock when it grants a lock so the VFS can find out which locks are locally held and do the correct lock cleanup when required. The underlying filesystem must not drop the kernel lock or call ->lm_grant() before returning to the caller with a FILE_LOCK_DEFERRED return code.h]hXCallers expecting ->lock() to return asynchronously will only use F_SETLK, not F_SETLKW; they will set FL_SLEEP if (and only if) the request is for a blocking lock. When ->lock() does return asynchronously, it must return FILE_LOCK_DEFERRED, and call ->lm_grant() when the lock request completes.

**Description** This function walks the pages and the blocks within each page, building and emitting large BIOs. If anything unusual happens, such as: - encountering a page which has buffers - encountering a page which has a non-hole after a hole - encountering a page with non-contiguous blocks then this code just gives up and calls the buffer_head-based read function. It does handle a page which has holes at the end - that is a common case: the end-of-file on blocksize < PAGE_SIZE setups. BH_Boundary explanation: There is a problem. The mpage read code assembles several pages, gets all their disk mappings, and then submits them all. That's fine, but obtaining the disk mappings may require I/O. Reads of indirect blocks, for example. So an mpage read of the first 16 blocks of an ext2 file will cause I/O to be submitted in the following order: 12 0 1 2 3 4 5 6 7 8 9 10 11 13 14 15 16 because the indirect block has to be read to get the mappings of blocks 13,14,15,16. Obviously, this impacts performance. So what we do it to allow the filesystem's get_block() function to set BH_Boundary when it maps block 11. BH_Boundary says: mapping of the block after this one will require I/O against a block which is probably close to this one. So you should push what I/O you have currently accumulated. This all causes the disk requests to be issued in the correct order.h](h)}(h**Parameters**h]j)}(hjrWh]h Parameters}(hjtWhhhNhNubah}(h]h ]h"]h$]h&]uh1jhjpWubah}(h]h

If ``__GFP_DIRECT_RECLAIM`` is set then bio_alloc will always be able to allocate a bio. This is due to the mempool guarantees. To make this work, callers must never allocate more than 1 bio at a time from the general pool. Callers that need to allocate more than 1 bio must always submit the previously allocated bio for IO before attempting to allocate a new one. Failure to do so can cause deadlocks under memory pressure. Note that when running under submit_bio_noacct() (i.e. any block driver), bios are not submitted until after you return - see the code in submit_bio_noacct() that converts recursion into iteration, to prevent stack overflows.

attempt of an inode finishes and undoes wbc_attach_and_unlock_inode(). Can be called under any context. As concurrent write sharing of an inode is expected to be very rare and memcg only tracks page ownership on first-use basis severely confining the usefulness of such sharing, cgroup writeback tracks ownership per-inode. While the support for concurrent write sharing of an inode is deemed unnecessary, an inode being written to by different cgroups at different points in time is a lot more common, and, more importantly, charging only by first-use can too readily lead to grossly incorrect behaviors (single foreign page can lead to gigabytes of writeback to be incorrectly attributed). To resolve this issue, cgroup writeback detects the majority dirtier of an inode and transfers the ownership to it. To avoid unnecessary oscillation, the detection mechanism keeps track of history and gives out the switch verdict only if the foreign usage pattern is stable over a certain amount of time and/or writeback attempts. On each writeback attempt, **wbc** tries to detect the majority writer using Boyer-Moore majority vote algorithm. In addition to the byte count from the majority voting, it also counts the bytes written for the current wb and the last round's winner wb (max of last round's current wb, the winner from two rounds ago, and the last round's majority candidate). Keeping track of the historical winner helps the algorithm to semi-reliably detect the most active writer even when it's not the absolute majority. Once the winner of the round is determined, whether the winner is foreign or not and how much IO time the round consumed is recorded in inode->i_wb_frn_history. If the amount of recorded foreign IO time is over a certain threshold, the switch verdict is given.h](h)}(h**Parameters**h]j)}(hj^h]h Parameters}(hj^hhhNhNubah}(h]h ]h"]h$]h&]uh1jhj^ubah}(h]h ]h"]h$]h&]uh1hhY/var/lib/git/docbuild/linux/Documentation/filesystems/api-summary:71: ./fs/fs-writeback.chMwhj^ubj)}(hhh]j)}(hS``struct writeback_control *wbc`` writeback_control of the just finished writeback h](j)}(h!``struct writeback_control *wbc``h]j)}(hj_h]hstruct writeback_control *wbc}(hj_hhhNhNubah}(h]h ]h"]h$]h&]uh1jhj_ubah}(h]h ]h"]h$]h&]uh1jhY/var/lib/git/docbuild/linux/Documentation/filesystems/api-summary:71: ./fs/fs-writeback.chMthj^ubj)}(hhh]h)}(h0writeback_control of the just finished writebackh]h0writeback_control of the just finished writeback}(hj_hhhNhNubah}(h]h ]h"]h$]h&]uh1hhj_hMthj_ubah}(h]h ]h"]h$]h&]uh1jhj^ubeh}(h]h ]h"]h$]h&]uh1jhj_hMthj^ubah}(h]h ]h"]h$]h&]uh1jhj^ubh)}(h**Description**h]j)}(hj>_h]h Description}(hj@_hhhNhNubah}(h]h ]h"]h$]h&]uh1jhj<_ubah}(h]h ]h"]h$]h&]uh1hhY/var/lib/git/docbuild/linux/Documentation/filesystems/api-summary:71: ./fs/fs-writeback.chMvhj^ubh)}(hTo be called after a writeback attempt of an inode finishes and undoes wbc_attach_and_unlock_inode().

This function will return a pointer to a dentry if it succeeds. This pointer must be passed to the debugfs_remove() function when the file is to be removed (no automatic cleanup happens if your module is unloaded, you are responsible here.) If an error occurs, ERR_PTR(-ERROR) will be returned. If debugfs is not enabled in the kernel, the value -``ENODEV`` will be returned. **NOTE** it's expected that most callers should _ignore_ the errors returned by this function.

callback inside of it must be initialized **Description** When a debugfs file is removed it needs to wait for all active operations to complete. However, the operation itself may need to wait for hardware or completion of some asynchronous process or similar. As such, it may need to be cancelled to avoid long waits or even deadlocks. This function can be used inside a debugfs handler that may need to be cancelled.
