From 963b72fc6664be12ea52f35a6addea14ec373433 Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Sat, 3 Oct 2009 19:42:18 +0200 Subject: [PATCH] cfq-iosched: rename 'desktop' sysfs entry to 'low_latency' Don't think that's necessarily a perfect description of what this option fiddles with, but it's probably better than 'desktop'.
