NFSv4: Avoid unnecessary scans of filesystems for expired delegations

Browse source

[ Upstream commit f163aa81a7 ]

The amount of looping through the list of delegations is occasionally
leading to soft lockups.  If the state manager was asked to reap the
expired delegations, it should scan only those filesystems that hold
delegations that need to be reaped.
