From: Taylor Jackson <tjackson9431@xxxxxxxxx> Within the vfs test for idmapped mounts, the function nested_userns() is using an incorrect array index when attempting to set up the mapping for the 4th nested user ns within hierarchy[4]. The correct index that belongs to the 4th nested user ns is actually hierarchy[3]. And hierarchy[4] is reserved for the dummy entry that marks the end of the array.
