Subject: [GIT PULL] Btrfs fixes for v6.0-rc3

Hi,

a few more fixes and regressions. Please pull, thanks.

- fixes:
  - check that subvolume is writable when changing xattrs from security
    namespace
  - fix memory leak in device lookup helper
  - update generation of hole file extent item when merging holes
  - fix space cache corruption and potential double allocations; this is
    a rare bug but can be serious once it happens, stable backports and
    analysis tool will be provided
  - fix error handling when deleting root references
  - fix crash due to assert when attempting to cancel suspended device
    replace, add message what to do if mount fails due to missing
    replace item

- regressions:
  - don't merge pages into bio if their page offset is not contiguous
  - don't allow large NOWAIT direct reads, this could lead to short
    reads eg. in io_uring
