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
