Subject: [PATCH 01/10] bpf samples: bpf: Fix tracex5_kern.c compiling error
Date: Thu, 17 Dec 2015 05:23:05 +0000	[thread overview]
Message-ID: <1450329794-161948-2-git-send-email-wangnan0@huawei.com> (raw)
In-Reply-To: <1450329794-161948-1-git-send-email-wangnan0@huawei.com>

LLVM report compiling error:

 /kpathsamples/bpf/tracex5_kern.c:33:15: error: use of undeclared identifier '__NR_getuid'; did you
       mean '__NR_vgetcpu'?
         if (sd.nr >= __NR_getuid && sd.nr <= __NR_getsid) {
                      ^~~~~~~~~~~
                      __NR_vgetcpu
 /kpath/arch/x86/include/uapi/asm/vsyscall.h:7:2: note: '__NR_vgetcpu' declared here
         __NR_vgetcpu,

This patch fix it by adding asm/unistd.h to it.
