* git://git.kernel.org/pub/scm/linux/kernel/git/sfrench/cifs-2.6: (31 commits)
[CIFS] Remove redundant test
[CIFS] make sure that DFS pathnames are properly formed
Remove an already-checked error condition in SendReceiveBlockingLock
Streamline SendReceiveBlockingLock: Use "goto out:" in an error condition
Streamline SendReceiveBlockingLock: Use "goto out:" in an error condition
[CIFS] Streamline SendReceive[2] by using "goto out:" in an error condition
Slightly streamline SendReceive[2]
Check the return value of cifs_sign_smb[2]
[CIFS] Cleanup: Move the check for too large R/W requests
[CIFS] Slightly simplify wait_for_free_request(), remove an unnecessary "else" branch
Simplify allocate_mid() slightly: Remove some unnecessary "else" branches
[CIFS] In SendReceive, move consistency check out of the mutexed region
cifs: store password in tcon
cifs: have calc_lanman_hash take more granular args
cifs: zero out session password before freeing it
cifs: fix wait_for_response to time out sleeping processes correctly
[CIFS] Can not mount with prefixpath if root directory of share is inaccessible
[CIFS] various minor cleanups pointed out by checkpatch script
[CIFS] fix typo
[CIFS] remove sparse warning
...
Fix trivial conflict in fs/cifs/cifs_fs_sb.h due to comment changes for
the CIFS_MOUNT_xyz bit definitions between cifs updates and security
updates.
