Subject: Re: 回复: [PATCH v5] workqueue: Remove unnecessary kfree() call in rcu_free_wq()
Date: Thu, 28 May 2020 12:57:03 +0300	[thread overview]
Message-ID: <20200528095703.GH30374@kadam> (raw)
In-Reply-To: <DM6PR11MB3257D6E7E93A518392502809FF8E0@DM6PR11MB3257.namprd11.prod.outlook.com>

Guys, the patch is wrong.  The kfree is harmless when this is called
from destroy_workqueue() and required when it's called from
pwq_unbound_release_workfn().  Lai Jiangshan already explained this
already.  Why are we still discussing this?

regards,
dan carpenter
