Date: Sat, 7 Nov 2015 12:43:48 +0800 From: Geliang Tang <geliangtang@....com> To: Matt Fleming <matt@...eblueprint.co.uk>, Anton Vorontsov <anton@...msg.org>, Colin Cross <ccross@...roid.com>, Kees Cook <keescook@...omium.org>, Tony Luck <tony.luck@...el.com> Cc: Geliang Tang <geliangtang@....com>, linux-efi@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH v2 2/3] efi-pstore: implement efivars_pstore_exit() The original efivars_pstore_exit() is empty. I 1) add a bufsize check statement. 2) call pstore_unregister as it is defined now. 3) free the memory and set bufsize to 0.
