* git://git.kernel.org/pub/scm/linux/kernel/git/sfrench/cifs-2.6:
  cifs: make sure we allocate enough storage for socket address
  [CIFS] Make socket retry timeouts consistent between blocking and nonblocking cases
  [CIFS] some cleanup to dir.c prior to addition of posix_open
  [CIFS] revalidate parent inode when rmdir done within that directory
  [CIFS] Rename md5 functions to avoid collision with new rt modules
  cifs: turn smb_send into a wrapper around smb_sendv

@ -5,7 +5,9 @@ rather than posix (advisory) byte range locks, even though server would
support posix byte range locks. Fix query of root inode when prefixpath
specified and user does not have access to query information about the
top of the share. Fix problem in 2.6.28 resolving DFS paths to
Samba servers (worked to Windows).
Samba servers (worked to Windows). Fix rmdir so that pending search
(readdir) requests do not get invalid results which include the now
removed directory.

Similarly we wait for 15 seconds for
a response from the server in SendReceive[2]

most types of requests (except SMB Write
past end of file which can be slow, and
blocking lock operations). NFS waits slightly longer
than CIFS, but this can make it take longer for
nonresponsive servers to be detected and 15 seconds
is more than enough time for modern networks to
