The patch titled
lguest: documentation and example updates
has been removed from the -mm tree. Its filename was
lguest-documentation-and-example-updates.patch
This patch was dropped because it was folded into
lguest-the-documentation-example-launcher.patch
------------------------------------------------------
Subject: lguest: documentation and example updates
From: Rusty Russell <[EMAIL PROTECTED]>
1) Example code: old libc headers don't have SIOCBRADDIF, and old zlibs
don't have gzdirect() -- it's a sanity check anyway.
2) Some people don't build in their source directories, so .config
isn't there (thanks to Tony Breeds <[EMAIL PROTECTED]>).
3) Point out that guest and host kernel are usually the same.
4) Set the "no checksum" option on the tun device as a minor optimization.
