Yes, LTTng (the kernel tracer) can trace syscall entry and exit events,
and then you can isolate the calls related to your process.
If you use UST (the userspace tracer) then you can trace whatever you
want from your application.

Technically yes. It has been ported to Linaro for example.
Someone was looking into porting LTTng to Android some months ago, but
we haven't heard anything in a while.
