H A D | dir.c | 49317a7f Sun Jul 13 20:28:20 CDT 2014 NeilBrown <neilb@suse.de> NFS: nfs4_lookup_revalidate: only evaluate parent if it will be used.
nfs4_lookup_revalidate only uses 'parent' to get 'dir', and only uses 'dir' if 'inode == NULL'.
So we don't need to find out what 'parent' or 'dir' is until we know that 'inode' is NULL.
By moving 'dget_parent' inside the 'if', we can reduce the number of call sites for 'dput(parent)'.
