Date: Thu, 05 Nov 2015 11:36:47 +0900 From: Hiraku Toyooka <hiraku.toyooka.gu@...achi.com> To: linux-kernel@...r.kernel.org Cc: Tony Luck <tony.luck@...el.com>, Kees Cook <keescook@...omium.org>, Seiji Aguchi <seiji.aguchi.tr@...achi.com>, Mark Salyzyn <salyzyn@...roid.com>, Anton Vorontsov <anton@...msg.org>, Colin Cross <ccross@...roid.com> Subject: [PATCH 1/5] ramoops: use persistent_ram_free() instead of kfree() for freeing prz persistent_ram_zone(=prz) structures are allocated by persistent_ram_new(), which includes vmap() or ioremap(). But they are currently freed by kfree(). We should use persistent_ram_free() to correct this asymmetry usage.
