From: Trond Myklebust Date: Mon, 30 Jun 2014 15:48:34 +0000 (-0400) Subject: nfsd: nfs4_preprocess_seqid_op should only set *stpp on success X-Git-Tag: v3.17-rc1~58^2~142 X-Git-Url: http://git.cascardo.info/?a=commitdiff_plain;h=e17f99b728006fcebcf025b32fa7370bb998fb81;p=cascardo%2Flinux.git nfsd: nfs4_preprocess_seqid_op should only set *stpp on success Not technically a bugfix, since nothing tries to use the return pointer if this function doesn't return success, but it could be a problem with some coming changes.
