From 4ba9b9d0ba0a49d91fa6417c7510ee36f48cf957 Mon Sep 17 00:00:00 2001 From: Christoph Lameter Date: Tue, 16 Oct 2007 23:25:51 -0700 Subject: Slab API: remove useless ctor parameter and reorder parameters Slab constructors currently have a flags parameter that is never used. And the order of the arguments is opposite to other slab functions. The object pointer is placed before the kmem_cache pointer. Convert ctor(void *object, struct kmem_cache *s, unsigned long flags) to ctor(struct kmem_cache *s, void *object) throughout the kernel [akpm@linux-foundation.org: coupla fixes] Signed-off-by: Christoph Lameter Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- mm/slab.c | 11 +++++------ 1 file changed, 5 insertions(+), 6 deletions(-) (limited to 'mm/slab.c') diff --git a/mm/slab.c b/mm/slab.c index e34bcb87a6ee..18fa1a65f57b 100644 --- a/mm/slab.c +++ b/mm/slab.c @@ -408,7 +408,7 @@ struct kmem_cache { unsigned int dflags; /* dynamic flags */ /* constructor func */ - void (*ctor) (void *, struct kmem_cache *, unsigned long); + void (*ctor)(struct kmem_cache *, void *); /* 5) cache creation/removal */ const char *name; @@ -2129,7 +2129,7 @@ static int __init_refok setup_cpu_cache(struct kmem_cache *cachep) struct kmem_cache * kmem_cache_create (const char *name, size_t size, size_t align, unsigned long flags, - void (*ctor)(void*, struct kmem_cache *, unsigned long)) + void (*ctor)(struct kmem_cache *, void *)) { size_t left_over, slab_size, ralign; struct kmem_cache *cachep = NULL, *pc; @@ -2636,8 +2636,7 @@ static void cache_init_objs(struct kmem_cache *cachep, * They must also be threaded. */ if (cachep->ctor && !(cachep->flags & SLAB_POISON)) - cachep->ctor(objp + obj_offset(cachep), cachep, - 0); + cachep->ctor(cachep, objp + obj_offset(cachep)); if (cachep->flags & SLAB_RED_ZONE) { if (*dbg_redzone2(cachep, objp) != RED_INACTIVE) @@ -2653,7 +2652,7 @@ static void cache_init_objs(struct kmem_cache *cachep, cachep->buffer_size / PAGE_SIZE, 0); #else if (cachep->ctor) - cachep->ctor(objp, cachep, 0); + cachep->ctor(cachep, objp); #endif slab_bufctl(slabp)[i] = i + 1; } @@ -3078,7 +3077,7 @@ static void *cache_alloc_debugcheck_after(struct kmem_cache *cachep, #endif objp += obj_offset(cachep); if (cachep->ctor && cachep->flags & SLAB_POISON) - cachep->ctor(objp, cachep, 0); + cachep->ctor(cachep, objp); #if ARCH_SLAB_MINALIGN if ((u32)objp & (ARCH_SLAB_MINALIGN-1)) { printk(KERN_ERR "0x%p: not aligned to ARCH_SLAB_MINALIGN=%d\n", -- cgit v1.2.3
