Subject: [PATCH V3 0/2] SLUB bulk API interactions with kmem cgroup
Date: Mon, 09 Nov 2015 19:16:58 +0100 [thread overview]
Message-ID: <20151109181604.8231.22983.stgit@firesoul> (raw)
In-Reply-To: <20151105161048.GG29259@esperanza>
Added correct support for kmem cgroup interaction with SLUB bulk API.
I've compiled kernel with CONFIG_MEMCG_KMEM=y, and have tested the
kernel with the setup provide by Vladimir Davydov. And with my
network stack use-case patchset applied, to actually activate the API.
Patch01: I've verified the loop in slab_post_alloc_hook() gets removed
by the compiler (when no debug options defined). This was actually
tricky due to kernel gcc compile options, and I wrote a small program
to figure this out [1].
Patch02: The "try_crash" mode of the test module slab_bulk_test03 [2]
have been modified as after this change we no longer handle error
cases like passing of NULL pointers in the array to free, when
CONFIG_MEMCG_KMEM is enabled.
