The patch titled
lguest: trivial guest network driver (fix)
has been removed from the -mm tree. Its filename was
lguest-trivial-guest-network-driver-fix.patch
This patch was dropped because it was folded into lguest-trivial-guest-network-driver.patch
------------------------------------------------------
Subject: lguest: trivial guest network driver (fix)
From: Rusty Russell <rusty@xxxxxxxxxxxxxxx>
Thanks to Herbert Xu for noticing the bug: "len" here is skb_headlen(),
not skb->len. Renamed the function to clarify, too.
