From 1344dd86f35c7669c94aceb2273676e356cff848 Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Fri, 3 Mar 2017 17:45:38 -0800 Subject: [PATCH] pstore: Avoid race in module unloading Technically, it might be possible for struct pstore_info to go out of scope after the module_put(), so report the backend name first.
