From 3f776e8a25a9d281125490562e1cc5bd7c14cf7c Mon Sep 17 00:00:00 2001 From: Anton Blanchard Date: Tue, 30 Oct 2007 14:57:43 -0700 Subject: [PATCH] IB/fmr_pool: Stop ib_fmr threads from contributing to load average I noticed my machine was at a constant load average of 1. This was because ib_create_fmr_pool calls kthread_create but does not immediately wake the thread up. Change to using kthread_run so we enter ib_fmr_cleanup_thread(), set TASK_INTERRUPTIBLE, then go to sleep.
