Merge branch 'for-next' of git://git.samba.org/sfrench/cifs-2.6
Pull CIFS fixes from Steve French:
"This includes a set of misc. cifs fixes (most importantly some byte
range lock related write fixes from Pavel, and some ACL and idmap
related fixes from Jeff) but also includes the SMB2.02 dialect
enablement, and a key fix for SMB3 mounts.
Default authentication upgraded to ntlmv2 for cifs (it was already
ntlmv2 for smb2)"

cifs: fix hardcoded default security descriptor length
cifs: extra sanity checking for cifs.idmap keys
cifs: avoid extra allocation for small cifs.idmap keys
