Pull ext4 updates from Ted Ts'o: "Add support for buffered iomap support in ext4. This is not enabled by default, but requires the buffered_iomap mount option, as this mode does not support online defragmentation, inline data, fsverify, fscrypt, non-extent inodes, and data=journal mode. If buffered_iomap is enabled, ext4 will fall back to the original I/O code path automatically if necessary. Large writes show significant performance improvements when buffered iomap is enabled. There are also miscellaneous bug fixes and improvements, including for fast commit and avoiding deadlocks and out-of-bound reads when handling corner cases involving corrupted file systems" * tag 'ext4_for_linus-7.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4: (41 commits) ext4: introduce a mount option for iomap buffered I/O path ext4: partially enable iomap for the buffered I/O path of regular files ext4: add tracepoints for EOF block zeroing and disksize-grow I/O ext4: add tracepoints for DISKSIZE_GROW_PENDING set, clear, and wait ext4: set DISKSIZE_GROW_PENDING after zeroing unaligned EOF block ext4: clear DISKSIZE_GROW_PENDING on truncate or error ext4: submit and wait for disksize-grow I/O in fallocate paths ext4: defer i_disksize update while DISKSIZE_GROW_PENDING is set ext4: advance i_disksize to i_size upon disksize-grow I/O completion ext4: submit and wait for pending disksize-grow I/O on writeback ext4: add EXT4_STATE_DISKSIZE_GROW_PENDING state bit and helpers ext4: disable online defrag when inode using iomap buffered I/O path ext4: add block mapping tracepoints for iomap buffered I/O path ext4: drain writeback before removing extents on the iomap path ext4: implement partial block zero range path using iomap ext4: implement mmap path using iomap ext4: implement writeback path using iomap ext4: rework handle credit accounting for unwritten extent conversion ext4: implement buffered write path using iomap ext4: do not use data=ordered mode for inodes using buffered iomap path ...
