[PATCH 0/4] btrfs: fixes for reclaim

[Naohiro Aota <naota@elisp.net>]

There are several issues on the reclaim process out there:

 - Long-running reclaim process blocks removing unused BGs
 - Belonging to the reclaim list blocks it goes to the unused list
 - It tries relocation even when FS is read-only
 - Temporal failure keep a block group un-reclaimed

This series fixes them.

Naohiro Aota (4):
  btrfs: delete unused BGs while reclaiming BGs
  btrfs: move out now unused BG from the reclaim list
  btrfs: bail out reclaim process if filesystem is read-only
  btrfs: reinsert BGs failed to reclaim
