Subject: IO queuing and complete affinity with threads (was Re: [PATCH 0/8] IO queuing and complete affinity)

Date: Thursday, February 7, 2008 - 2:25 pm

Hi,

Here's a variant using kernel threads only, the nasty arch bits are then
not needed. Works for me, no performance testing (that's a hint for Alan
to try and queue up some testing for this variant as well :-)
