Subject: cifs: escape spaces in share names
From: Maciek Borzecki <maciek.borzecki@xxxxxxxxx>
commit 0fc9322ab5e1fe6910c9673e1a7ff29f7dd72611 upstream.
Commit 653a5efb849a ("cifs: update super_operations to show_devname")
introduced the display of devname for cifs mounts. However, when mounting
a share which has a whitespace in the name, that exact share name is also
displayed in mountinfo. Make sure that all whitespace is escaped.
