Merge git://git.kernel.org/pub/scm/linux/kernel/git/sfrench/cifs-2.6
* git://git.kernel.org/pub/scm/linux/kernel/git/sfrench/cifs-2.6: [CIFS] remove unknown mount option warning message [CIFS] remove bkl usage from umount begin cifs: Fix incorrect return code being printed in cFYI messages [CIFS] cleanup asn handling for ntlmssp [CIFS] Copy struct *after* setting the port, instead of before. cifs: remove rw/ro options cifs: fix problems with earlier patches cifs: have cifs parse scope_id out of IPv6 addresses and use it [CIFS] Do not send tree disconnect if session is already disconnected [CIFS] Fix build break cifs: display scopeid in /proc/mounts cifs: add new routine for converting AF_INET and AF_INET6 addrs cifs: have cifs_show_options show forceuid/forcegid options cifs: remove unneeded NULL checks from cifs_show_options
