* 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.
