Message-Id: <1422411777-22332-1-git-send-email-sasha.levin@oracle.com> Date: Tue, 27 Jan 2015 21:22:54 -0500 From: Sasha Levin <sasha.levin@...cle.com> To: linux-kernel@...r.kernel.org Cc: iamjoonsoo.kim@....com, m.szyprowski@...sung.com, akpm@...ux-foundation.org, lauraa@...eaurora.org, Sasha Levin <sasha.levin@...cle.com> Subject: [PATCH v3 0/3] mm: cma: debugfs access to CMA I've noticed that there is no interfaces exposed by CMA which would let me fuzz what's going on in there. This small patch set exposes some information out to userspace, plus adds the ability to trigger allocation and freeing from userspace. Changes from v2: - Keep allocated memory lists per-cma - Don't allow partial free with non-zero order_per_bit - Use 0 alignment Changes from v1: - Make allocation and free hooks per-cma. - Remove additional debug prints.
