From: Masami Hiramatsu Date: Thu, 16 Mar 2017 23:40:21 +0000 (-0700) Subject: kasan: add a prototype of task_struct to avoid warning X-Git-Tag: v4.9.174~49 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=51a27f037fb328d55389252ae67bcc2b9d70e7ac;p=platform%2Fkernel%2Flinux-amlogic.git kasan: add a prototype of task_struct to avoid warning commit 5be9b730b09c45c358bbfe7f51d254e306cccc07 upstream. 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.
