[CIFS]
Allow Windows blocking locks to be cancelled via a CANCEL_LOCK call. TODO - restrict this to servers that support NT_STATUS codes (Win9x will probably not support this call). Signed-off-by: Jeremy Allison <jra@samba.org> Signed-off-by: Steve French <sfrench@us.ibm.com> (cherry picked from 570d4d2d895569825d0d017d4e76b51138f68864 commit)
