From e539d8fcd11af811db70707d47ea436d5621d0da Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Thu, 5 Jun 2008 10:28:00 +0200 Subject: [PATCH] sched: fix the cpuprio count really Peter pointed out that the last version of the "fix" was still one off under certain circumstances. Use BITS_TO_LONG instead to get an accurate result.
