SRU Justification: Impact: Unionfs cause kernel crash
Fix Description: This fixes a problem with chown'ing a file which has the suid bit set and has more than one hardlink on a read-only file system. The stacked nature of the unionfs means that the attribute changes pass through the lower level attr fs routines with the ATTR_MODE flag set when it's already been handled before in a stacked operation, so clear the ATTR_MODE flag. (This is the same fix as in the stacked ecrypt fs.)
