[PATCH v3 0/5] btrfs-progs: scrub interface
This is the next patch series for scrub userland tools.
Change log v1->v2:
- commands now reachable as "btrfs scrub ..." instead of "btrfs filesystem
scrub ..."
- ability to scrub a single device instead of a whole file system
- superfluous command line options removed
- resume is now a separate command ("scrub resume") instead of "scrub start -r"
