Why not do something like the below?...Yep, sounds like a good approach, thanks. Percpu partial is not *the* SLUB fast path, so it should be sufficient without the lockless cmpxchg tricks. Will incorporate in updated series.
The updated series incorporating hopefully all fixes from Mike and bigeasy, and rebased to 5.14-rc3 (Thomas told me RT is moving to it), is here: https://git.kernel.org/pub/scm/linux/kernel/git/vbabka/linux.git/log/?h=slub-local-lock-v3r0 I'll post it to linux-mm tomorrow.
