Miklos Szeredi 708fa01597 ovl: allow upperdir inside lowerdir ... Commit 146d62e5a5 ("ovl: detect overlapping layers") made sure we don't have overlapping layers, but it also broke the arguably valid use case of mount -olowerdir=/,upperdir=/subdir,.. where upperdir overlaps lowerdir on the same filesystem. This has been causing regressions. Revert the check, but only for the specific case where upperdir and/or workdir are subdirectories of lowerdir. Any other overlap (e.g. lowerdir is subdirectory of upperdir, etc) case is crazy, so leave the check in place for those. Overlaps are detected at lookup time too, so reverting the mount time check should be safe.
