Access grab state of evdev device
I need to retrieved the grab state of an evdev device in a program. More specifically, I need to retrieve the state of the grab
pointer in the evdev
struct seen here: https://elixir.bootlin.com/linux/v4.20/source/drivers/input/evdev.c#L42 (if it is NULL or not NULL). Is this at all possible from userspace, e.g. through reading kernel memory with /dev/(k)mem or do I need to write a kernel module? Where should I get started?
