search for: groups_sem

...h again, with loop == 2. If we come full circle and haven''t found what we need then we exit with -ENOSPC. I''ve been running this for a couple of days now and it seems stable, and I haven''t yet hit a -ENOSPC when there was plenty of space left. Also I''ve made a groups_sem to handle the group list for the space_info. This is part of my locking changes, but is relatively safe and seems better than holding the space_info spinlock over that entire search time.

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.
