See the remark from Dave [1] that the patch in its current form seems to be incomplete. Also FS people were not involved properly to evaluate all the potential fallouts. Even if the only way forward is to "cripple" IOCB_NOWAIT then the documentation should go along with the change rather than suprise people much later when the system behaves unexpectedly. So I _think_ this patch is not really ready yet. Also I haven't heard any discussion whether we can reduce the effect of the change in a similar way we do for mincore. > Merging patch just patch 1 withouth patch 2 is probably sort of useless > excercise, unfortunately. Why would that be the case. We know that mincore is the simplest way _right now_. Closing it makes sense on its own.
