Subject: [PATCH v7 0/2] mm/slab, ipc: kmem_buckets kernel-doc and msg_msg accounting fixes
Date: Tue, 13 Oct 2026 22:23:41 -0700 [thread overview]
Message-ID: <20261014052338.nothing.279-kees@kernel.org> (raw)
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!
-Kees
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
