I looked at slab.h in various kernel and see this function
extern unsigned int kmem_cache_size(kmem_cache_t *);
which returns buffer_size that is set by kmem_cache_create() to size.
So the backport will look like:
static inline
void *kmem_cache_zalloc(kmem_cache_t *cache, gfp_t flags)
{
void *ret = kmem_cache_alloc(cache, flags);
if (ret)
memset(ret, 0, kmem_cache_size(cache));
return ret;
}
Would you agree? Do I oversee something else?
