Doc Type: Bug Fix
Doc Text:
.Creating same dentries after the unlink finishes does not crash the MDS daemons Previously, there was a racy condition between unlink and creating operations. Due to this, if the previous unlink request was delayed due to any reasons, and creating same dentries was attempted during this time, it would fail by crashing the MDS daemons or new creation would succeed but the written content would be lost. With this fix, users need to ensure to wait until the unlink finishes, to avoid conflict when creating the same dentries.
