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
