Hi agl, evan,

Sorry for asking review, but I couldn't find a reviewer for this kind of patch.
(I'd appreciate if you could suggest reviewers)

Thanks,

behdad is probably the right reviewer, but neither of us can reasonably review
if we can't see the bug I'm afraid.

It's a trivial OOB.  LGTM, and I upstreamed it.

No LGTM from a valid reviewer yet. Only full committers are accepted.
Even if an LGTM may have been provided, it was from a non-committer or
a lowly provisional committer, _not_ a full super star committer.
See http://www.chromium.org/getting-involved/become-a-committer
Note that this has nothing to do with OWNERS files.
