init_timer() deprecated for linux versions >4.15

[sutble]

Heads up, when trying to build this library on newer versions of the linux kernel, some of the functions that this library needs are deprecated.

I have the same problem. Surprised there's no changes here.

Same here. Can't compile this on long-term-support Ubuntu (20.04).

It's a pity, it seems really useful.
