[PATCH] Optimise NFS readdir hack slightly.
Avoid calling the underlying ->readdir() again when we reached the end already; keep going round the loop only if we stopped due to our own buffer being full. [AV: tidy the things up a bit, while we are there] Signed-off-by: David Woodhouse <David.Woodhouse@intel.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
