Subject: nfsd: move unhash_client_locked call into mark_client_expired_locked
X-Git-Url: http://git.efficios.com/?a=commitdiff_plain;h=97403d95e1a7f5b257e90aad1f3284953bc72671;p=deliverable%2Flinux.git

nfsd: move unhash_client_locked call into mark_client_expired_locked

All the callers except for the fault injection code call it directly
afterward, and in the fault injection case it won't hurt to do so
anyway.
