Merge tag 'mm-hotfixes-stable-2023-06-20-12-31' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm
Pull hotfixes from Andrew Morton:
"19 hotfixes. 8 of these are cc:stable.
This includes a wholesale reversion of the post-6.4 series 'make slab
shrink lockless'. After input from Dave Chinner it has been decided
that we should go a different way [1]"
