From a13cda3e7a332b57823986b4705216ea5ee1509f Mon Sep 17 00:00:00 2001 From: Wade Farnsworth Date: Tue, 2 Oct 2012 17:08:30 +0100 Subject: [PATCH] ARM: 7548/1: include linux/sched.h in syscall.h commit 8ef102c6b4bc996ff96ca52b34775fe931ec90c9 upstream. The syscall tracing patch introduces a compile bug in lttng-modules when the latter calls syscall_get_nr(), similar to the following: /arch/arm/include/asm/syscall.h:21:2: error: implicit declaration of function 'task_thread_info' [-Werror=implicit-function-declaration] The issue is that we are using task_thread_info() in the syscall_get_nr() function in asm/syscall.h, but not explicitly including sched.h from this file, so we can expect this bug might surface any time that syscall_get_nr() is called. Explicitly including sched.h solves the problem.
