The fix has been merged into master and will be backported soon.

Amazing, thanks!


I've
also done testing in a large cluster to confirm the issue you found.
Using multiple processes to create files as fast as possible in a
single client reliably reproduced the issue. The MDS cannot recall
capabilities fast enough when the internal upkeep thread ran every 5
seconds. Moving the cache trimming and capability recall to a separate
thread running every second resolved the issue.
