Subject: [PATCH v2 0/8] xen/events: bug fixes and some diagnostic aids
Date:   Thu, 11 Feb 2021 11:16:08 +0100

The first four patches are fixes for XSA-332. The avoid WARN splats
and a performance issue with interdomain events.

Patches 5 and 6 are some additions to event handling in order to add
some per pv-device statistics to sysfs and the ability to have a per
backend device spurious event delay control.

Patches 7 and 8 are minor fixes I had lying around.

Juergen Gross (8):
  xen/events: reset affinity of 2-level event when tearing it down
  xen/events: don't unmask an event channel when an eoi is pending
  xen/events: avoid handling the same event on two cpus at the same time
  xen/netback: fix spurious event detection for common event case
  xen/events: link interdomain events to associated xenbus device
  xen/events: add per-xenbus device event statistics and settings
  xen/evtchn: use smp barriers for user event ring
  xen/evtchn: use READ/WRITE_ONCE() for accessing ring indices
