Pull ext4 updates from Ted Ts'o:
- Improve performance by allowing parallel DIO writes when we were
previously being overly conservative when checking whether it was
safe to avoid requiring an exclusive lock
- Improve the performance of ext4_mb_prefetch() used by fallocate() by
avoiding work when it is not needed
- Remove the unnecessary custom end_io function
ext4_end_buffer_io_sync()
- Improve performance when performing an overwrite to an already
uptodate folio
- Clean up how we handle deallocating EA inodes to avoid a potential
lock ordering issue when there is a failed mount while an EA inode is
still being evicted
- Use str_plural() instead of a custom macro
- Avoid soft lockups or RCU stalls if there are many busy buffers
(caused by heavy I/O) while checkpointing
- Use scoped NOFS when starting a handle in nojournal mode
- Align fields in handle structure to optimize setting and getting the
h_type and h_line_no fields
- Fix documentation of the meta_bg block group layout
- Bug fixes:
- Fix a potential out-of-bounds read in ext4_read_inline_dir()
- Fix a potential deadlock when concurrent xattr operations are
racing with each other when some of the xattrs are using the
ea_inode feature
- Fix a spurious warning with data=journal that can be triggered
when writeback races with remounting the file system read-only
- Fix a potential deadlock when EXT4_IOC_MIGRATE races with a file
system freeze operation
- Make sure all in-flight direct I/O operations are complete before
falling back to buffered I/O
- Handle IOCB_NOWAIT properly when performing a extending DAX write
- Prevent potentially sleeping on a block allocation when
IOCB_NOWAIT is set
- Fix potential races when racing an inline data write with a page
fault
- Propagate errors when adding or removing extent ranges during a
fast commit replay
- Avoid trying to expand an inode's extra size when it is being
evicted to avoid a number of corner case or deadlocks
- Avoid spurious error when retrying inode extra size expansion
- Fix corner cases where we underestimate the number of journal
credits needed
- Avoid hangs/crashes/WARNINGS caused by maliciously corrupted file
systems
- Don't issue spurious orphan clean message on RO file systems
- Avoid leaving the file system in an inconsistent state after a
crash when a WRITE_ZEROS in progress converting an unwritten
extent to a written extent
- Handle WRITE_ZEROS correctly when there are some partially dirtied
regions in the page cache
- Pass errors during zero-rage, truncate, or punch hole to the
caller if ext4_get_block() fails
- Wait for writeback to finish when triggered by zero-range or
zero-range for those devices that require stable writes
- If the reserved gid superblock field is set, set the reserved gid
instead of the reserved uid
