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
