Subject[GIT PULL] Btrfs fixes for 5.0-rc5
Date
Hi,

there are a few fixes that I'd like to have in the 5.0 release. Last rc
was skipped because one fix had to be reworked and more testing was
needed. Please pull, thanks.

- regression fix: transaction commit can run away due to delayed ref
waiting heuristic, this is not necessary now because of the proper
reservation mechanism introduced in 5.0

- regression fix: potential crash due to use-before-check of an ERR_PTR
return value

- fix for transaction abort during transaction commit that needs to
properly clean up pending block groups

- fix deadlock during b-tree node/leaf splitting, when this happens on
some of the fundamental trees, we must prevent new tree block
allocation to re-enter indirectly via the block group flushing path

- potential memory leak after errors during mount

----------------------------------------------------------------
The following changes since commit fd340d0f68cc87badfc9efcb226f23a5428826a0:
