H A Drelay.rst4 relay interface (formerly relayfs)
7 The relay interface provides a means for kernel applications to

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

24 buffer data. The relay interface doesn't implement any form of data
