Message-ID: <5614979C.30100@lge.com> Date: Wed, 7 Oct 2015 12:55:08 +0900 From: Jongsung Kim <neidhard.kim@....com> To: Nicolas Pitre <nicolas.pitre@...aro.org>, Russell King - ARM Linux <linux@....linux.org.uk> Cc: Chanho Min <chanho.min@....com>, linux-arm-kernel@...ts.infradead.org, linux-kernel@...r.kernel.org, Gunho Lee <gunho.lee@....com> Subject: Re: [PATCH] ARM:mm: fix kmap_atomic_to_page Recently, we made a driver utilizing kmap_atomic_to_page. Of course, it's not mainlined. People may be using it outside mainline just like us. vmalloc has vmalloc_to_page, pkmap has kmap_to page, and fixmap has kmap_atomic_to_page. Then.. how about letting virt_to_page do them all?
