Why do you want to do this way? Can you explain the need for this kind of design more in detail? Did you check if there are any concurrency issues/race conditions when your kernel module is accesing your user-space memory ?
Hi,
i know it is possible with an ioctl to change a value in a kernel module.
Is it possible to let a kernel module change a value in user space when
some kind of error occurs?
so that i dont need to check 'if' an error occured.
Christian.
Normally, returning special error codes from kernel-space and taking actions according to them is a cleaner and safer design.
