Linux 6.4 to Feature Faster Btrfs Scrub Code

The Btrfs scrub code used for verifying checksums and repairing damaged blocks is seeing improvements in the upcoming Linux 6.4 release. SUSE engineer Qu Wenruo has streamlined the code to address existing problems and improve performance, including reducing jumps and inefficient IOPS for fragmented extents. Expect to see these and other Btrfs improvements in the Linux 6.4 merge window in a few weeks.
