Hi all,
To make reviewing and updating easier, I've chosen to split the previous
patchset[1] into the following three parts:
part 1: some cleanups and preparations
part 2: introduce new APIs and convert all shrinnkers to use these
part 3: implement lockless slab shrink
This series is the part 1 and is based on the next-20230815.
Comments and suggestions are welcome.

Hi all,
Any more comments and suggestions for this part 1? Or can this part
be merged first (just some cleanups and preparations)? Or should I
post the part 2 and part 3 first for everyone to review together?
Either one is fine for me. :)
Thanks,
Qi
