| |
hi,
The following is an implementation of Frederic's syscall tracer on top of tracepoints. 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
