Merge tag 'fs-for_v6.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs

Pull ext2, udf, reiserfs, and quota updates from Jan Kara:

 - Fix for udf to make splicing work again

 - More disk format sanity checks for ext2 to avoid crashes found by
   syzbot

 - More quota disk format checks to avoid crashes found by fuzzing

 - Reiserfs & isofs cleanups

* tag 'fs-for_v6.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs:
  quota: Add more checking after reading from quota file
  quota: Replace all block number checking with helper function
  quota: Check next/prev free block number after reading from quota file
  ext2: Use kvmalloc() for group descriptor array
  ext2: Add sanity checks for group and filesystem size
  udf: Support splicing to file
  isofs: delete unnecessary checks before brelse()
  fs/reiserfs: replace ternary operator with min() and min_t()
