MD RAID Optimizations, Btrfs Fixes For Linux 4.11
Written by Michael Larabel in Linux Storage on 25 February 2017 at 07:06 AM EST. 6 Comments
The MD pull request was submitted on Friday for the Linux 4.11 kernel as were the Btrfs file-system changes.

Chris Mason's pull request of new feature material for Linux 4.11 wasn't particularly exciting. The Btrfs updates primarily include fixes and code clean-ups. There's been a lot of code polishing and fixing that happened by multiple developers, but not much in the way of new feature work.

Meanwhile, Shaohua Li submitted the MD pull request. The MD changes for Linux 4.11 include scalability improvements for RAID1, improved RAID5 cache read performance and greater disk efficiency and I/O patterns, race condition fixes, a memory leak fix, and other code improvements.
