Could you include the link to the forum post.

I guess his signed-off-by line additionally to yours (Tested-by: is also
good) would not hurt.

Sorry, unfortunately I cannot tell you why your work has not been
committed yet and I do understand your frustration. The reasons might be
simple, that the developers were caught up by different things and your
patch just fall through the cracks. So it is a good thing, that you come
back and ask for the status.

So to ease work for the developers, could you please resend your patch.
Do you know if it can be split up, so that the controversial parts can
be left out at first?

Please use `git format-patch` with

1. a short commit summary line,
2. links to the respective Web pages where this patch was discussed.

You can just copy the lines from the resulting file into a normal
message (delete the header fields and copy the subject manually marking
it with [RESENT]). Just make sure the lines do not get wrapped.

Then make sure to CC the maintainers (I think Clemens, Takashi,
Jaroslav) too so that they do not miss it.

I hope your patch will be included soon afterward.

Thanks and good luck,
