From b2c18e1e08a5a9663094d57bb4be2f02226ee61c Mon Sep 17 00:00:00 2001 From: Jeff Moyer Date: Fri, 23 Oct 2009 17:14:49 -0400 Subject: cfq: calculate the seek_mean per cfq_queue not per cfq_io_context async cfq_queue's are already shared between processes within the same priority, and forthcoming patches will change the mapping of cic to sync cfq_queue from 1:1 to 1:N. So, calculate the seekiness of a process based on the cfq_queue instead of the cfq_io_context.
