Merge tag 'fs_for_v6.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs

Pull misc filesystem updates from Jan Kara:

 - Rewrite kmap_local() handling in ext2

 - Convert ext2 direct IO path to iomap (with some infrastructure tweaks
   associated with that)

 - Convert two boilerplate licenses in udf to SPDX identifiers

 - Other small udf, ext2, and quota fixes and cleanups

* tag 'fs_for_v6.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs:
  udf: Fix uninitialized array access for some pathnames
  ext2: Drop fragment support
  quota: fix warning in dqgrab()
  quota: Properly disable quotas when add_dquot_ref() fails
  fs: udf: udftime: Replace LGPL boilerplate with SPDX identifier
  fs: udf: Replace GPL 2.0 boilerplate license notice with SPDX identifier
  fs: Drop wait_unfrozen wait queue
  ext2_find_entry()/ext2_dotdot(): callers don't need page_addr anymore
  ext2_{set_link,delete_entry}(): don't bother with page_addr
  ext2_put_page(): accept any pointer within the page
  ext2_get_page(): saner type
  ext2: use offset_in_page() instead of open-coding it as subtraction
  ext2_rename(): set_link and delete_entry may fail
  ext2: Add direct-io trace points
  ext2: Move direct-io to use iomap
  ext2: Use generic_buffers_fsync() implementation
  ext4: Use generic_buffers_fsync_noflush() implementation
  fs/buffer.c: Add generic_buffers_fsync*() implementation
  ext2/dax: Fix ext2_setsize when len is page aligned
