[GIT PULL] Btrfs fixes for 5.13-rc5

[David Sterba]

Hi,

this is a batch from last week, I wanted to give it more testing because
last pull request introduced a bug, interacting zoned and subpage
features. Otherwise there are error handling improvements and bug
fixes. The last commit is from today, adding IRC link to maintainers
file.

Please pull, thanks.

- error handling improvements, caught by error injection
  - handle errors during checksum deletion
  - set error on mapping when ordered extent io cannot be finished
  - inode link count fixup in tree-log
  - missing return value checks for inode updates in tree-log
  - abort transaction in rename exchange if adding second reference fails

- fixes
  - fix fsync failure after writes to prealloc extents
  - fix deadlock when cloning inline extents and low on available space
  - fix compressed writes that cross stripe boundary
