ovl_setattr () used to pass -1 as uid or gid when either of them is not changed for do_fchown () / do_chown (), but if these functions use overriding xattrs instead of real fchown () or chown (), it causes -1 to be written in owner overriding xattrs and break them. Replace -1 with the current uid or gid before calling do_fchown () / do_chown (). Signed-off-by: Akihiko Odaki <odaki@rsg.ci.i.u-tokyo.ac.jp>
