Brian King 38f1852759 [PATCH] block: CFQ refcounting fix ... I ran across a memory leak related to the cfq scheduler. The cfq init function increments the refcnt of the associated request_queue. This refcount gets decremented in cfq's exit function. Since blk_cleanup_queue only calls the elevator exit function when its refcnt goes to zero, the request_q never gets cleaned up. It didn't look like other io schedulers were incrementing this refcnt, so I removed the refcnt increment and it fixed the memory leak for me. To reproduce the problem, simply use cfq and use the scsi_host scan sysfs attribute to scan "- - -" repeatedly on a scsi host and watch the memory vanish.
