Indeed, it's quite surprising that we seem to be the only project
affected by this issue. Yesterday, my colleague Alexandre Belloni, who
maintains the kernel RTC subsystem, sent a 100 patches patch series to
the Linux RTC mailing list, and all of the patches were recorded by
patchwork. On the other hand, someone sent a 6 patches patch series on
the Buildroot mailing list yesterday, and only 2 out of the 6 patches
were recorded by patchwork.

However, I believe the RTC mailing list is using Google Groups, while
we are using a mailman hosted at OSUOSL, which perhaps is sending
e-mail faster than Google Groups.

Anyway, looking forward to seeing those fixes deployed on ozlabs.org!

Thanks again!
