Paolo 'Blaisorblade' Giarrusso 4833aff757 [PATCH] uml: allow again to move backing file and to override saved location 
When the user specifies both a COW file and its backing file, if the previous
backing file is not found, currently UML tries again to use it and fails.

This can be corrected by changing same_backing_files() return value in that
case, so that the caller will try to change the COW file to point to the new
location, as already done in other cases.

Additionally, given the change in the meaning of the func, change its name,
invert its return value, so all values are inverted except when
stat(from_cow,&buf2) fails.  And add some comments and two minor bugfixes -
remove a fd leak (return err rather than goto out) and a repeated check.

Tested well.
