Hi,
The previous version (RFC, no cover letter) is here: https://lore.kernel.org/all/20220826090912.11292-1-vbabka@suse.cz/
Git branch is here: https://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab.git/log/?h=slab/for-6.2/fit_rcu_head (also in linux-next since late last week)
The rationale for doing all this is in patch 3 - I hope there are still plans for the rcu_head debugging, Joel?
The previous version was in linux-next, which brought crash reports due to causing false positive __PageMovable() tests. There were several attempts to deal with it, as explained in Patch 2, which is an updated version of one of those attempts. It hasn't been formally posted and reviewed yet, hence this posting.
Thanks, Vlastimil
