Subject: [PATCH v2 0/5] use refcount+RCU method to implement lockless slab shrink (part 1)
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.

Thanks,
Qi
