Message

Hi all,

This series is some cleanups split from the previous patchset[1], I dropped the
[PATCH v2 5/5] which is more related to the main lockless patch.

This series is based on the next-20230823.

Comments and suggestions are welcome.

Hi Andrew,

Can this cleanup series be merged? This part is relatively independent
and has Reviewed-bys and Acked-by.

Thanks,
Qi
