Hi,

please pull the following fixes, thanks.

- fix regression in extent map rework when handling insertion of
  overlapping compressed extent

- fix unexpected file length when appending to a file using direct io
  and buffer not faulted in

- in zoned mode, fix accounting of unusable space when flipping
  read-only block group back to read-write

- fix page locking when COWing an inline range, assertion failure found
  by syzbot

- fix calculation of space info in debugging print

- tree-checker, add validation of data reference item

- fix a few -Wmaybe-uninitialized build warnings
