From e48f891e9f50367586669085ceca155d05478a9f Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Mon, 28 Sep 2015 01:34:21 +0100 Subject: [PATCH] rtsx_usb_ms: Use msleep_interruptible() in polling loop rtsx_usb_ms creates a task that mostly sleeps, but tasks in uninterruptible sleep still contribute to the load average (for bug-compatibility with Unix). A load average of ~1 on a system that should be idle is somewhat alarming. Change the sleep to be interruptible, but still ignore signals. A better fix might be to replace this loop with a delayed work item.
