Subject: [GIT PULL] Btrfs fixes for 5.5-rc5

Hi,

a few fixes for btrfs:

* blkcg accounting problem with compression that could stall writes

* setting up blkcg bio for compression crashes due to NULL bdev pointer

* fix possible infinite loop in writeback for nocow files (here possible
  means almost impossible, 13 things that need to happen to trigger it)

Please pull, thanks.
