[PATCH 2/3] tracing/syscalls: Fix typo in SYSCALL_DEFINE0

[Steven Rostedt <rostedt@goodmis.org>]

[-- Attachment #1: 0002-tracing-syscalls-Fix-typo-in-SYSCALL_DEFINE0.patch --]
[-- Type: text/plain, Size: 1208 bytes --]

From: Lai Jiangshan <laijs@cn.fujitsu.com>

The struct syscall_metadata variable name in SYSCALL_DEFINE0
should be __syscall_meta__##sname instead of __syscall_meta_##sname
to match the name that is in SYSCALL_DEFINE1/2/3/4/5/6.

This error causes event_enter_##sname->data to point to the wrong
location, which causes syscalls which are defined by SYSCALL_DEFINE0()
not to be traced.
