The compensation, in Linux anyways, is that others will review your code if you review theirs. So the motivation to review stuff on the mailing list is purely that you need someone to review your code to get it in.
It sounds like quid pro quo but I found the level of review (e.g. for the DRM subsystem) to be excellent, even if it's one AMD eng reviewing some other AMD engineers code in the AMD specific code.
