From 9a035a40f7f3f6708b79224b86c5777a3334f7ea Mon Sep 17 00:00:00 2001
From: Jan Beulich <JBeulich@suse.com>

Subject: [PATCH] xenbus: don't look up transaction IDs for ordinary writes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Organization: Invisible Things Lab
Cc: Marek Marczykowski-Górecki <marmarek@invisiblethingslab.com>
This should really only be done for XS_TRANSACTION_END messages, or
else at least some of the xenstore-* tools don't work anymore.
Fixes: 0beef634b8 ("xenbus: don't BUG() on user mode induced condition")
