From 34af946a22724c4e2b204957f2b24b22a0fb121c Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Tue, 27 Jun 2006 02:53:55 -0700 Subject: [PATCH] spin/rwlock init cleanups locking init cleanups: - convert " = SPIN_LOCK_UNLOCKED" to spin_lock_init() or DEFINE_SPINLOCK() - convert rwlocks in a similar manner this patch was generated automatically. Motivation: - cleanliness - lockdep needs control of lock initialization, which the open-coded variants do not give - it's also useful for -rt and for lock debugging in general Signed-off-by: Ingo Molnar Signed-off-by: Arjan van de Ven Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- mm/sparse.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'mm/sparse.c') diff --git a/mm/sparse.c b/mm/sparse.c index e0a3fe48aa3..c7a2b3a0e46 100644 --- a/mm/sparse.c +++ b/mm/sparse.c @@ -45,7 +45,7 @@ static struct mem_section *sparse_index_alloc(int nid) static int sparse_index_init(unsigned long section_nr, int nid) { - static spinlock_t index_init_lock = SPIN_LOCK_UNLOCKED; + static DEFINE_SPINLOCK(index_init_lock); unsigned long root = SECTION_NR_TO_ROOT(section_nr); struct mem_section *section; int ret = 0; -- cgit v1.2.3
