From 7318226ea2931a627f3572e5f4804c91ca19ecbc Mon Sep 17 00:00:00 2001 From: David Howells Date: Thu, 26 Apr 2007 15:46:23 -0700 Subject: [AF_RXRPC]: Key facility changes for AF_RXRPC Export the keyring key type definition and document its availability. Add alternative types into the key's type_data union to make it more useful. Not all users necessarily want to use it as a list_head (AF_RXRPC doesn't, for example), so make it clear that it can be used in other ways. Signed-off-by: David Howells Signed-off-by: David S.
