Subject: [GIT PULL] slab fix for 6.19-rc1
Date: Wed, 10 Dec 2025 11:11:08 +0100 [thread overview]
Message-ID: <80e63358-3016-4208-bfc5-242f201d4f94@suse.cz> (raw)
Hi Linus,
please pull the slab fix from:
git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab.git tags/slab-for-6.19-rc1
Fixing this perf regression in rc1 should save time for people integration-
testing new code on top of it.
Thanks,
Vlastimil
======================================
- A stable fix for performance regression in tests that perform
kmem_cache_destroy() a lot, due to unnecessarily wide scope
of kvfree_rcu_barrier(). (Harry Yoo)
