Subject: [PATCH 0/2] xen: bug fixes in Xen backend handling
Date: Fri, 29 Jul 2016 13:17:29 +0200 [thread overview]
Message-ID: <1469791051-680-1-git-send-email-jgross@suse.com> (raw)
When testing qemu based pvusb backend two bugs have been discovered:
- detaching of a usb controller leads to memory clobbering in qemu
- detaching of a usb device with active I/O requests could result in
crash of qemu
Juergen Gross (2):
xen: when removing a backend don't remove many of them
xen: drain submit queue in xen-usb before removing device
