Subject: [GIT PULL] Btrfs fixes for 6.10-rc3, part 2

Hi,

a few more fixes, two are for serious problems which are hard to hit,
details in the changelogs. Please pull, thanks.

- fix handling of folio private changes, the private value holds pointer
  to our extent buffer structure representing a metadata range, release
  and create of the range was not properly synchronized when updating
  the private bit which ended up in double folio_put, leading to all
  sorts of breakage

- fix a crash, reported as duplicate key in metadata, but caused by a
  race of fsync and size extending write, requires prealloc target
  range + fsync and other conditions (log tree state, timing)

- fix leak of qgroup extent records after transaction abort

----------------------------------------------------------------
The following changes since commit f13e01b89daf42330a4a722f451e48c3e2edfc8d:
