Prev: [PATCH 20/40] trace syscalls: Considder compat_syscall_nr when verifying syscall_nr
Next: [PATCH 14/40] compat: convert to use COMPAT_SYSCALL_DEFINE#N()
From: Ian Munsie on 23 Jun 2010 06:20
From: Jason Baron <jbaron(a)redhat.com>

trace_syscalls.c uses __start_ftrace_events and __stop_ftrace_events in order
to prune compat syscall ftrace events that are not referenced by the compat
syscall table. So move the 'extern' definitions to a common header file.
