Merge branch 'for-next' of git://git.samba.org/sfrench/cifs-2.6
Pull CIFS fixes from Steve French:
"Three small CIFS Fixes (the most important of the three fixes a recent
problem authenticating to Windows 8 using cifs rather than SMB2)"
* 'for-next' of git://git.samba.org/sfrench/cifs-2.6:
cifs: ignore everything in SPNEGO blob after mechTypes
cifs: delay super block destruction until all cifsFileInfo objects are gone
cifs: map NT_STATUS_SHARING_VIOLATION to EBUSY instead of ETXTBSY
