XFS In Linux 4.10 Contains DAX iomap Support, Other Updates
The XFS feature updates for Linux 4.10 include making use of the iomap infrastructure that landed with the EXT4 pull. So XFS now has a new direct I/O implementation making use of iomap, which should be "simpler, faster, and has lower IO latency."
Aside from the iomap-related work there are also other code changes, optimized CRC calculations, faster buffer cache lookups, and various fixes.
More details on the XFS changes for Linux 4.10 via this pull request. This is also the last pull request from Dave Chinner for a while as he's going on a ~7 month holiday, so for that period Darrick Wong is stepping up as XFS maintainer.
