Subject: [GIT PULL] Btrfs updates for 5.12-rc2

From: David Sterba <dsterba@...e.cz>

Hi,

first batch of fixes that usually arrive during the merge window code
freeze. Regressions and stable material. Please pull, thanks.

Regressions:

- fix deadlock in log sync in zoned mode

- fix bugs in subpage mode still wrongly assuming sectorsize == page
  size

Fixes:

- fix missing kunmap of the Q stripe in RAID6

- block group fixes:
  - fix race between extent freeing/allocation when using bitmaps
  - avoid double put of block group when emptying cluster

- swapfile fixes:
  - fix swapfile writes vs running scrub
  - fix swapfile activation vs snapshot creation

- fix stale data exposure after cloning a hole with NO_HOLES enabled

- remove tree-checker check that does not work in case information from
  other leaves is necessary
