commit 5326de9e94bedcf7366e7e7625d4deb8c1f1ca8a upstream.
If nfs4_delegreturn_prepare needs to wait for a layoutreturn to complete then make sure we drop the sequence slot if we hold it.
Fixes: 1c5bd76d17cc ("pNFS: Enable layoutreturn operation for return-on-close") Signed-off-by: Trond Myklebust trond.myklebust@hammerspace.com Signed-off-by: Greg Kroah-Hartman gregkh@linuxfoundation.org
