The patch titled
Slab API: remove useless ctor parameter and reorder parameters
has been removed from the -mm tree. Its filename was
slab-api-remove-useless-ctor-parameter-and-reorder-parameters.patch
This patch was dropped because it had testing failures
------------------------------------------------------
Subject: Slab API: remove useless ctor parameter and reorder parameters
From: Christoph Lameter <clameter@xxxxxxx>
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
Signed-off-by: Christoph Lameter <clameter@xxxxxxx>
