Drelay.rst4 relay interface (formerly relayfs)
7 The relay interface provides a means for kernel applications to
9 to userspace via user-defined 'relay channels'.
11 A 'relay channel' is a kernel->user data relay mechanism implemented
13 represented as a regular file ('relay file') in user space. Kernel

17 and retrieve the data as it becomes available. The relay files
22 up to the kernel client; the relay interface does however provide
24 buffer data. The relay interface doesn't implement any form of data
