[PATCH] cifs: Do not sleep interruptible after socket connect failure

======================

To permit users to ummount directories that they have user mounted (see above),

the utility umount.cifs may be used.  It may be invoked directly, or if 

umount.cifs is placed in /sbin, umount -i can invoke the cifs umount helper

umount.cifs is placed in /sbin, umount can invoke the cifs umount helper

(at least for most versions of the umount utility) for umount of cifs

mounts. As with mount.cifs, to enable user unmounts umount.cifs must be marked

as suid (e.g. "chmod +s /sbin/umount.cifs").  For this utility to succeed

the target path must be a cifs mount, and the uid of the current user must

match the uid of the user who mounted the resource.

mounts, unless umount is invoked with -i (which will avoid invoking a umount

helper). As with mount.cifs, to enable user unmounts umount.cifs must be marked

as suid (e.g. "chmod +s /sbin/umount.cifs") or equivalent (some distributions

allow adding entries to a file to the /etc/permissions file to achieve the

equivalent suid effect).  For this utility to succeed the target path

must be a cifs mount, and the uid of the current user must match the uid

of the user who mounted the resource.

Also note that the customary way of allowing user mounts and unmounts is 

(instead of using mount.cifs and unmount.cifs as suid) to add a line

		This has no effect if the server does not support

		Unicode on the wire.

 nomapchars     Do not translate any of these seven characters (default).

 remount        remount the share (often used to change from ro to rw mounts

	        or vice versa)

The mount.cifs mount helper also accepts a few mount options before -o

including:
