From 5be9b730b09c45c358bbfe7f51d254e306cccc07 Mon Sep 17 00:00:00 2001 From: Masami Hiramatsu Date: Thu, 16 Mar 2017 16:40:21 -0700 Subject: [PATCH] kasan: add a prototype of task_struct to avoid warning Add a prototype of task_struct to fix below warning on arm64. In file included from arch/arm64/kernel/probes/kprobes.c:19:0: include/linux/kasan.h:81:132: error: 'struct task_struct' declared inside parameter list will not be visible outside of this definition or declaration [-Werror] static inline void kasan_unpoison_task_stack(struct task_struct *task) {} As same as other types (kmem_cache, page, and vm_struct) this adds a prototype of task_struct data structure on top of kasan.h. [arnd] A related warning was fixed before, but now appears in a different line in the same file in v4.11-rc2. The patch from Masami Hiramatsu still seems appropriate, so let's take his version.
