Here's an updated version based on feedback so I don't re-send everything so soon after v2. Also in git: https://git.kernel.org/pub/scm/linux/kernel/git/vbabka/linux.git/log/?h=slub-stackdepot-v3r0 There are only trivial adaptations in patch 3/6 to the stack depot init changes otherwise. Thanks, Vlastimil ----8<----
