Merge tag 'fs_for_v5.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs

Pull UDF, reiserfs, ext2, quota fixes from Jan Kara:

 - a couple of UDF fixes for issues found by syzbot fuzzing

 - a couple of reiserfs fixes for issues found by syzbot fuzzing

 - some minor ext2 cleanups

 - quota patches to support grace times beyond year 2038 for XFS quota
   APIs

* tag 'fs_for_v5.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs:
  reiserfs: Fix oops during mount
  udf: Limit sparing table size
  udf: Remove pointless union in udf_inode_info
  udf: Avoid accessing uninitialized data on failed inode read
  quota: clear padding in v2r1_mem2diskdqb()
  reiserfs: Initialize inode keys properly
  udf: Fix memory leak when mounting
  udf: Remove redundant initialization of variable ret
  reiserfs: only call unlock_new_inode() if I_NEW
  ext2: Fix some kernel-doc warnings in balloc.c
  quota: Expand comment describing d_itimer
  quota: widen timestamps for the fs_disk_quota structure
  reiserfs: Fix memory leak in reiserfs_parse_options()
  udf: Use kvzalloc() in udf_sb_alloc_bitmap()
  ext2: remove duplicate include
