Making kernel do the right thing automatically sounds like a better option to me. > 2. This patch, as is, may be a bit problematic.

I don't think this should be a problem, given the fact that the whole timing/ordering is not predictable anyway due to scheduling. Paul, what do you think? Thanks, -- Jiri Kosina SUSE Labs
