Btrfs In Linux 4.4 Has Many Improvements/Fixes

Written by Michael Larabel in Linux Storage on 6 November 2015 at 02:46 PM EST. 38 Comments

Chris Mason sent in the pull request today for updating the Btrfs file-system for Linux 4.4.

The Btrfs file-system in Linux 4.4 has a number of sub-volume quota improvements, many code clean-ups, and a number of allocator fixes based upon their usage at Facebook. The allocator fixes should also help improve the RAID 5/6 performance when the file-system is mounted with ssd_spread as previously it hit some CPU bottlenecks.

More details on the tons of Btrfs file-system changes slated for Linux 4.4 can be found via this kernel mailing list message.
