Subject: knfsd: Remove dead code from nfsd_cache_lookup
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=3e87da5145fc25e18fb934eb496f4e7c4d038e71;p=openwrt%2Fstaging%2Fblogic.git

knfsd: Remove dead code from nfsd_cache_lookup

The preallocated cache entry is always set to type RC_NOCACHE, and that
type isn't changed until we later call nfsd_cache_update().
