From 04f432f47b906e129209daf8e505ac0f6b57ebd0 Mon Sep 17 00:00:00 2001 From: Grissiom Date: Sat, 21 Dec 2013 11:31:40 +0800 Subject: [PATCH] kernel: let rt_thread_idle_excute loop until there is no dead thread Out side world is difficult to tell whethere there is dead thread remaining. If rt_thread_idle_excute only do one cleanup, it's hard to finish cleanups outside the idle thread. So let is loop and do all the cleanups in one call. --- src/idle.c | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) diff --git a/src/idle.c b/src/idle.c index ff3fde21c..7bca6c28c 100644 --- a/src/idle.c +++ b/src/idle.c @@ -22,6 +22,8 @@ * 2006-03-23 Bernard the first version * 2010-11-10 Bernard add cleanup callback function in thread exit. * 2012-12-29 Bernard fix compiling warning. + * 2013-12-21 Grissiom let rt_thread_idle_excute loop until there is no + * dead thread. */ #include @@ -72,8 +74,9 @@ void rt_thread_idle_sethook(void (*hook)(void)) */ void rt_thread_idle_excute(void) { - /* check the defunct thread list */ - if (!rt_list_isempty(&rt_thread_defunct)) + /* Loop until there is no dead thread.
