From 716ea3a7aae3a2bfc44cb97b5419c1c9868c7bc9 Mon Sep 17 00:00:00 2001 From: David Howells Date: Mon, 2 Apr 2007 20:19:53 -0700 Subject: [NET]: Move generic skbuff stuff from XFRM code to generic code Move generic skbuff stuff from XFRM code to generic code so that AF_RXRPC can use it too. The kdoc comments I've attached to the functions needs to be checked by whoever wrote them as I had to make some guesses about the workings of these functions.
