[PATCH 00/21] [RFC] Btrfs: restriper
Hello,
This patch series adds an initial implementation of restriper (it''s a
clever name for relocation framework that allows to do selective profile
changing and selective balancing with some goodies like pausing/resuming
and reporting progress to the user.
Profile changing is global (per-FS) so far, per-subvolume profiles
require some discussion and can be implemented in future.
