SubjectRe: [PATCH 4/7 V2] workqueue: reuse the current per-node pwq when its attrs unchanged
Hi, TJ

The patch 4/5/6 does reduce cpu and temporary-memory usage sometimes.
But it is in slow path where small optimization is commonly unwelcome at.

Do I need to refactor the patches? I'm in doubt for the necessary.

Thanks,
Lai
