Subject: dmapool regression in next
Date: Wed, 5 Dec 2018 17:30:54 -0800	[thread overview]
Message-ID: <20181206013054.GI6707@atomide.com> (raw)

Hi,

Looks like with commit 26abe88e830d ("mm/dmapool.c: improve scalability
of dma_pool_free()") I'm now getting spammed with lots of "(bad vaddr)"
on at least omap4 pandaboard, see below.

Any ideas what might be going wrong?

Regards,

Tony
