[PATCH] nfs: allow nfs4_handle_delegation_recall_error() to silently handle -ERESTARTSYS

[Jeff Layton]

Currently, when a process stuck waiting on a delegrecall catches a
signal, it emits a scary looking printk():

    NFS: nfs4_handle_delegation_recall_error: unhandled error -512.

Allow nfs4_handle_delegation_recall_error() to accept and return that
value without the printk().
