When CIFS Unix Extensions are negotiated we get the Unix uid and gid owners of the file from the server (on the Unix Query Path Info levels), but if the server's uids don't match the client uid's users were having to disable the Unix Extensions (which turned off features they still wanted). The changeset patch allows users to override uid and/or gid for file/directory owner with a default uid and/or gid specified at mount (as is often done when mounting from Linux cifs client to Windows server). This changeset also displays the uid and gid used by default in /proc/mounts (if applicable). Also cleans up code by adding some of the missing spaces after "if" keywords per-kernel style guidelines (as suggested by Randy Dunlap when he reviewed the patch).
