[PATCH 3/4] mm/slab: make calculate_alignment() public

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Xiongwei Song <xiongwei.song@xxxxxxxxxxxxx>

We are going to move slab merge from slab_common.c to slub.c, there is a
call with it in find_mergeable(), so make it public.
