Subject: Re: [PATCH 4/7 V2] workqueue: reuse the current per-node pwq when its attrs unchanged
Date: Mon, 25 May 2015 17:47:17 +0800	[thread overview]
Message-ID: <5562EFA5.2030706@cn.fujitsu.com> (raw)

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
