From be4de35263f59ca1f4740edfffbfb02cc3f2189e Mon Sep 17 00:00:00 2001 From: Dave Chinner Date: Fri, 15 Aug 2008 00:40:44 -0700 Subject: completions: uninline try_wait_for_completion and completion_done m68k fails to build with these functions inlined in completion.h. Move them out of line into sched.c and export them to avoid this problem.
