I really like QEMU gdb server feature to debug the kernel but when I'm
working on cifs.ko (network filesystem) using breakpoints often means I
will trigger timeouts or mess with scheduled tasks.

I've found these slides [1] from 2014 that talk about adding a determinist
record and replay feature to QEMU even allowing reverse execution.

What's the status of that and if it's already available how do I use it?
