Merge tag 'for_v6.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs
Pull ext2, quota, and udf updates from Jan Kara: - fixes for possible use-after-free issues with quota when racing with chown - fixes for ext2 crashing when xattr allocation races with another block allocation to the same file from page writeback code - fix for block number overflow in ext2 - marking of reiserfs as obsolete in MAINTAINERS - assorted minor cleanups * tag 'for_v6.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs: ext2: Fix kernel-doc warnings ext2: improve consistency of ext2_fsblk_t datatype usage ext2: dump current reservation window info ext2: fix race between setxattr and write back ext2: introduce new flags argument for ext2_new_blocks() ext2: remove ext2_new_block() ext2: fix datatype of block number in ext2_xattr_set2() udf: Drop pointless aops assignment quota: use lockdep_assert_held_write in dquot_load_quota_sb MAINTAINERS: change reiserfs status to obsolete udf: Fix -Wstringop-overflow warnings quota: simplify drop_dquot_ref() quota: fix dqput() to follow the guarantees dquot_srcu should provide quota: add new helper dquot_active() quota: rename dquot_active() to inode_quota_active() quota: factor out dquot_write_dquot() ext2: remove redundant assignment to variable desc and variable best_desc
