Subject: cfq: calculate the seek_mean per cfq_queue not per cfq_io_context
X-Git-Tag: v2.6.33-rc1~379^2~88

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.
