#     Merge tag 'for-6.0-rc3-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
#     
#     Pull btrfs fixes from David Sterba:
#      "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"
#
