Merge tag 'fs_for_v6.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs

Pull ext2, reiserfs, udf, and quota updates from Jan Kara:
 "A couple of small fixes and cleanups for ext2, udf, reiserfs, and
  quota.

  The biggest change is making CONFIG_PRINT_QUOTA_WARNING depend on
  BROKEN with an outlook for removing it completely in an year or so"

* tag 'fs_for_v6.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs:
  quota: mark PRINT_QUOTA_WARNING as BROKEN
  quota: update Kconfig comment
  reiserfs: remove unused iter variable
  quota: Use register_sysctl_init() for registering fs_dqstats_table
  reiserfs: remove unused sched_count variable
  ext2: remove redundant assignment to pointer end
  quota: make dquot_set_dqinfo return errors from ->write_info
  quota: fixup *_write_file_info() to return proper error code
  quota: simplify two-level sysctl registration for fs_dqstats_table
  udf: use wrapper i_blocksize() in udf_discard_prealloc()
  udf: Use folios in udf_adinicb_writepage()
  ext2: Check block size validity during mount
  ext2: Correct maximum ext2 filesystem block size

If you say Y here, you will be able to set per user limits for disk
usage (also called disk quotas). Currently, it works for the
ext2, ext3, ext4, jfs, ocfs2 and reiserfs file systems.
ext2, ext3, ext4, f2fs, jfs, ocfs2 and reiserfs file systems.
Note that gfs2 and xfs use their own quota system.
Ext3, ext4 and reiserfs also support journaled quotas for which
