From 815f4e57e9fc67456624ecde0515a901368c78d2 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Wed, 12 Dec 2007 10:36:59 -0800 Subject: [IPSEC]: Make xfrm_lookup flags argument a bit-field This patch introduces an enum for bits in the flags argument of xfrm_lookup. This is so that we can cram more information into it later. Since all current users use just the values 0 and 1, XFRM_LOOKUP_WAIT has been added with the value 1 << 0 to represent the current meaning of flags. The test in __xfrm_lookup has been changed accordingly. Signed-off-by: Herbert Xu Signed-off-by: David S.
