Subject: nfsd: Convert nfs4_check_open_reclaim() to work with lookup_clientid()
X-Git-Tag: v3.17-rc1~58^2~127
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=0fe492db6003218d5c36765c09cce3a5a9f8a2eb;p=karo-tx-linux.git

nfsd: Convert nfs4_check_open_reclaim() to work with lookup_clientid()

lookup_clientid is preferable to find_confirmed_client since it's able
to use the cached client in the compound state.
