[GIT PULL 01/14 for v6.17] vfs misc

[Christian Brauner <brauner@kernel.org>]

Hey Linus,

/* Summary */
This contains the usual selections of misc updates for this cycle.

Features:

- Add ext4 IOCB_DONTCACHE support

  This refactors the address_space_operations write_begin() and
  write_end() callbacks to take const struct kiocb * as their first
  argument, allowing IOCB flags such as IOCB_DONTCACHE to propagate to
  the filesystem's buffered I/O path.

  Ext4 is updated to implement handling of the IOCB_DONTCACHE flag and
  advertises support via the FOP_DONTCACHE file operation flag.

  Additionally, the i915 driver's shmem write paths are updated to
  bypass the legacy write_begin/write_end interface in favor of directly
  calling write_iter() with a constructed synchronous kiocb. Another
  i915 change replaces a manual write loop with kernel_write() during
  GEM shmem object creation.

Cleanups:

- don't duplicate vfs_open() in kernel_file_open()

- proc_fd_getattr(): don't bother with S_ISDIR() check

- fs/ecryptfs: replace snprintf with sysfs_emit in show function

- vfs: Remove unnecessary list_for_each_entry_safe() from evict_inodes()

- filelock: add new locks_wake_up_waiter() helper

- fs: Remove three arguments from block_write_end()

- VFS: change old_dir and new_dir in struct renamedata to dentrys

- netfs: Remove unused declaration netfs_queue_write_request()

Fixes:

- eventpoll: Fix semi-unbounded recursion

- eventpoll: fix sphinx documentation build warning

- fs/read_write: Fix spelling typo

- fs: annotate data race between poll_schedule_timeout() and pollwake()

- fs/pipe: set FMODE_NOWAIT in create_pipe_files()

- docs/vfs: update references to i_mutex to i_rwsem

- fs/buffer: remove comment about hard sectorsize

- fs/buffer: remove the min and max limit checks in __getblk_slow()

- fs/libfs: don't assume blocksize <= PAGE_SIZE in generic_check_addressable

- fs_context: fix parameter name in infofc() macro

- fs: Prevent file descriptor table allocations exceeding INT_MAX
