Note: there is a fairly simple merge conflict, which can be resolved
by taking EXT4_SB(sb) and replacing it with sbi using the version in
your tree. My merge resolution (which I used to run regression tests)
is attached below.

ext4: remove expensive flush on fast commit (2021-01-15 14:41:31 -0500)
----------------------------------------------------------------
A number of bug fixes for ext4:
* For the new fast_commit feature
* Fix some error handling codepaths in whiteout handling and
mountpoint sampling
* Fix how we write ext4_error information so it goes through the journal
when journalling is active, to avoid races that can lead to lost
error information, superblock checksum failures, or DIF/DIX features.
----------------------------------------------------------------
Daejun Park (2):
ext4: fix wrong list_splice in ext4_fc_cleanup
ext4: remove expensive flush on fast commit
Jan Kara (7):
ext4: combine ext4_handle_error() and save_error_info()
ext4: drop sync argument of ext4_commit_super()
ext4: protect superblock modifications with a buffer lock
ext4: save error info to sb through journal if available
ext4: use sbi instead of EXT4_SB(sb) in ext4_update_super()
ext4: fix superblock checksum failure when setting password salt
ext4: drop ext4_handle_dirty_super()
Theodore Ts'o (1):
ext4: don't leak old mountpoint samples
Yi Li (1):
ext4: use IS_ERR instead of IS_ERR_OR_NULL and set inode null when IS_ERR
yangerkun (1):
ext4: fix bug for rename with RENAME_WHITEOUT
