Subject: Re: [PATCH] mm/slub: Flush virtual-slab work before cache destruction
Date: Sat, 14 Nov 2026 11:09:54 +0100	[thread overview]
Message-ID: <20261114100954.8262-1-f3lix.dev@gmx.de> (raw)
In-Reply-To: <179462737686.1463521.17920259642574913474@kernel.org>

Hi Harry,

Thank you for catching this. You're right: CONFIG_SLAB_VIRTUAL is not in
mainline.

This patch is against the public, out-of-tree SLAB_VIRTUAL feature branch:

https://github.com/thejh/linux/tree/slub-virtual-v7.2

I tested it on commit 699594e8888d (slub-virtual-v7.2-rc5), and confirmed
that the same issue is present in slub-virtual-v7.2. I intended the fix
for the feature authors to fold into a future revision of their series.

I failed to state that dependency in the subject and body, so the
standalone email misleadingly looked like a patch against upstream. That
was my mistake, sorry for the confusion.

Jann, Matteo, and Tamas, please let me know if you would prefer the fix
in a differently labeled or rebased form.

Thanks,
Felix
