Subject: Re: [PATCH] Fix a memory leak in scsi_host_dev_release()
Date: Fri, 20 Nov 2015 03:52:12 -0800	[thread overview]
Message-ID: <20151120115212.GA23875@infradead.org> (raw)

Hi Bart,

the memory leak looks real, and your fix looks corret, but I still
don't like it.

I think it's reasonable for SCSI to assume that the final put_device
fully frees the struct device including the name pointer that is
assigned entirely behind the back of the caller.

So I think the fix for this probably should be in the driver core.
