It adds the ability to toggle the entry/exit of each syscall via the standard events/syscalls/syscall_blah/enable interface. The implementation is done by adding 2 tracepoints. One on entry and one for exit. I've tried to address all of the comments from the last posting...updates include: -2/7: make arch_init_ftrace_syscalls static, removed locking, make patch bi-sectable -3/7: rename DECLARE_TRACE_REG as DECLARE_TRACE_WITH_CALLBACK -4/7: make mutex and counter static -7/7: add event tracing for syscalls that take no args thanks, -Jason arch/x86/include/asm/ftrace.h | 4 +- arch/x86/kernel/ftrace.c | 31 +++++--- arch/x86/kernel/ptrace.c | 6 +- include/linux/syscalls.h | 75 +++++++++++++++++- include/linux/tracepoint.h | 29 ++++++- include/trace/syscall.h | 37 +++++++--- kernel/trace/trace_events.c | 29 +++++--- kernel/trace/trace_syscalls.c | 172 +++++++++++++++++++---------------------- kernel/tracepoint.c | 38 +++++++++ 9 files changed, 289 insertions(+), 132 deletions(-)
