From 41f7f60d31e5e1dfc9a92957b3e14e08a2f04964 Mon Sep 17 00:00:00 2001 From: David Rientjes Date: Tue, 4 Mar 2008 23:32:38 -0800 Subject: [PATCH] cpusets: fix obsolete comment mm migration is no longer done in cpuset_update_task_memory_state() so it can no longer take current->mm->mmap_sem, so fix the obsolete comment. [ This changed in commit 04c19fa6f16047abff2288ddbc1f0798ede5a849 ("cpuset: migrate all tasks in cpuset at once") when the mm migration was moved from cpuset_update_task_memory_state() to update_nodemask() ] Signed-off-by: David Rientjes Cc: Paul Jackson Signed-off-by: Linus Torvalds --- kernel/cpuset.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/kernel/cpuset.c b/kernel/cpuset.c index 3e296ed81d4..a1b61f41422 100644 --- a/kernel/cpuset.c +++ b/kernel/cpuset.c @@ -322,8 +322,8 @@ static void guarantee_online_mems(const struct cpuset *cs, nodemask_t *pmask) * Call without callback_mutex or task_lock() held.
