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

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!
