Merge branch 'for-next' of git://git.samba.org/sfrench/cifs-2.6
Pull CIFS fixes from Steve French:
"A set of small cifs fixes, including 3 relating to symlink handling"
* 'for-next' of git://git.samba.org/sfrench/cifs-2.6:
cifs: don't instantiate new dentries in readdir for inodes that need to be revalidated immediately
cifs: set sb->s_d_op before calling d_make_root()
cifs: fix bad error handling in crypto code
cifs: file: initialize oparms.reconnect before using it
Do not attempt to do cifs operations reading symlinks with SMB2
cifs: extend the buffer length enought for sprintf() using
