Hi all,

I have a device driver that implements a mmap in a char device. I would like to know if is possible to get notified(in that kernel module) every time a process change its mapped memory. Does anyone know if so?

Regards, Erlon

You would come to know from the mmap file operation right?

Hi Erlon, I'm not sure but might be hardware watchpoints is what you need?

Maybe Deferred IO can help you. http://lwn.net/Articles/259210/ http://lwn.net/Articles/223751/ -- Kaspter Ju
