Subject: ovl: do not fail when setting origin xattr
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=6939f977c54a39207e94e429ee4eb14d4923736f;p=linux.git

ovl: do not fail when setting origin xattr

Comment above call already says this, but only EOPNOTSUPP is ignored, other
failures are not.

For example setting "user.*" will fail with EPERM on symlink/special.

Ignore this error as well.
