Hi,

oh right. Could you move the #ifdefs to the beginning of the line, not
indented, and post the patch inline in proper git style, please?

With that fixed:

I'm not sure it makes sense to #ifdef everything Linux specific, we use
stuff like signalfd and timerfd among other things, and epoll. Making
Weston portable outside Linux would be a much much bigger task, and I'm
not sure it is worth it.


Thanks,
