Indeed there's a lot wrong here. The idea of having an interruptible
sleep in probe() is arcane. You need a very, very, very good reason for that.Can you please explain why interruptible sleep should not be in probe() ?
I am curious to know.
-EINTR is supposed to be returned to user space, so that it can repeat
an interrupted syscall.
- There is no user space for probe()
- probe() cannot be easily repeated from user space
- there is no syscall for probe
