Subject: [PATCH] libxl: fix POLLHUP handling
Date: Thu, 31 Mar 2016 14:50:07 +0200 [thread overview]
Message-ID: <1459428607-5028-1-git-send-email-roger.pau@citrix.com> (raw)
The current code in bootloader_copyfail will error out on expected POLLHUPs
because of a missing "else" in the if clause.
The behaviour that triggers this bug has only been seen on FreeBSD so far.
