you are going to use a try and catch in the kernel?

Hi all,
I'm writing a kernel module, and am trying to implement some
exception-handling mechanism so that the system won't oops/panic if my
module does e.g. a NULL dereference. The (horribly hackish) way I'm
doing this right now is registering a die_notifier which will set the
'panic_on_oops'

I think asking in #linux-imx (freenode) would be a much better

You can try
We can put aside Java Memory Leak.
I downgraded to kernel 3.10.0-957.27.2.el7.x86_64, there are no more crashes.
The bug comes from ‘futex‘ syscall. What can causes that bug and how can i
investigate ?

My actual goal is to develop kernel space and user space programs to
establish communication in which kernel should initiate the communication.
The kernel will send information (e.g., guest physical address from
handle_ept_violation() in vmx.c, finding the corresponding page of that
address, owner
