Yeah, readx_poll_timeout_atomic is a mouthful, and then one also has to put in the name of the accessor... I'll wrap it when I respin the series, thanks. > Btw, given how few users of spin_event_timeout we have it might be good > idea to just kill it entirely. Maybe. That's for the ppc folks to comment on; the iopoll.h helpers are not completely equivalent (because obviously they don't read tbl directly). Maybe the generic versions should be taught spin_begin/spin_end/spin_cpu_relax so at least that part would be drop-in replacement. Rasmus
