I would like to implement a new kernel-modul with the ability to write data from kernelspace to userspace via the new relay subsystem. The less info from block/blktrace.c is insufficient unfortunately. The userspace-program should be able to "listen" to the kernel-modul if there is new data written. My first Implementation with data exchange over copy_to_user() and a char-device is insufficient. So i need an hint for something like blocked-IO for relay-files. Is this possible with the new relay-subsystem?
