Drelay.txt1 relay interface (formerly relayfs)
4 The relay interface provides a means for kernel applications to
6 to userspace via user-defined 'relay channels'.
8 A 'relay channel' is a kernel->user data relay mechanism implemented
10 represented as a regular file ('relay file') in user space. Kernel
13 buffer. User space applications mmap() or read() from the relay files
14 and retrieve the data as it becomes available. The relay files
19 up to the kernel client; the relay interface does however provide
21 buffer data. The relay interface doesn't implement any form of data
