From bd0d5aa417d40d6b996fb7b5c926bcecd56c8984 Mon Sep 17 00:00:00 2001 From: Jan Beulich Date: Mon, 5 Mar 2012 17:11:31 +0000 Subject: xenbus: don't free other end details too early The individual drivers' remove functions could legitimately attempt to access this information (for logging messages if nothing else). Note that I did not in fact observe a problem anywhere, but I came across this while looking into the reasons for what turned out to need the fix at https://lkml.org/lkml/2012/3/5/336 to vsprintf().
