[PATCH v7 0/2] mm/slab, ipc: kmem_buckets kernel-doc and msg_msg accounting fixes

[Kees Cook]

Hi!

As Vlastimil suggested[1], these are the first two patches of v6, split
out for 7.4. The rest of the skb buckets series will come back for 7.5.

2/2 now keeps SLAB_ACCOUNT on the msg_msg bucket caches and allocates
with GFP_KERNEL_ACCOUNT as well, so a msg_msg is charged with
CONFIG_SLAB_BUCKETS either way.

Thanks!

 v7:
 - split v6's 1/8 and 2/8 out for 7.4; 3/8 to 8/8 will return for 7.5
   (Vlastimil)
 - 2/2: keep SLAB_ACCOUNT in kmem_buckets_create(), and add Cc: stable
