From 33979734cd35ae0624337cdbc529921e4350d96f Mon Sep 17 00:00:00 2001 From: "akpm@osdl.org" Date: Tue, 27 Jun 2006 02:54:04 -0700 Subject: [PATCH] IPMI: use schedule in kthread Corey Minyard The kthread used to speed up polling for IPMI was using udelay in its busy-wait polling loop when the lower-level state machine told it to do a short delay. This just used CPU and didn't help scheduling, thus causing bad problems with other tasks. Call schedule() instead.
