Subject: [PATCH 02/24] KEYS: Disperse linux/key_ui.h [ver #7]
Date: Wed, 06 Aug 2008 16:37:24 +0100	[thread overview]
Message-ID: <20080806153724.14351.13817.stgit@warthog.procyon.org.uk> (raw)
In-Reply-To: <20080806153713.14351.91448.stgit@warthog.procyon.org.uk>

Disperse the bits of linux/key_ui.h as the reason they were put here (keyfs)
didn't get in.
