Doc Type: Bug Fix
Doc Text:
.Thread renaming no longer fails Previously, in a few rare cases, during renaming, if another thread tried to lookup the dst dentry, there were chances for it to get inconsistent result, wherein both the src dentry and dst dentry would link to the same inode simultaneously. Due to this,the rename request would fail as two different dentries were being linked to the same inode. With this fix, the thread waits for the renaming action to finish and everything works as expected.

Description Xiubo Li 2023-07-20 08:24:03 UTC 
In rare case during the rename if another thread tries to lookup the
dst dentry, it may get an inconsistent result that both src dentry
and dst dentry will link to the same inode at the same time.

Will wait the rename to finish and try it again.
