Merge branch 'for-next' of git://git.samba.org/sfrench/cifs-2.6
Pull CIFS fixes from Steve French: "Four cifs fixes (including for kernel bug #53221 and samba bug #9519)" * 'for-next' of git://git.samba.org/sfrench/cifs-2.6: cifs: bugfix for unreclaimed writeback pages in cifs_writev_requeue() cifs: set MAY_SIGN when sec=krb5 POSIX extensions disabled on client due to illegal O_EXCL flag sent to Samba cifs: ensure that cifs_get_root() only traverses directories
