      qemu: support Panic Crashloaded event handling · 26badd13
      由 zhenwei pi 提交于 
      Pvpanic device supports bit 1 as crashloaded event, it means that
guest actually panicked and run kexec to handle error by guest side.

Handle crashloaded as a lifecyle event in libvirt.

Test case:
Guest side:
before testing, we need make sure kdump is enabled,
1, build new pvpanic driver (with commit from upstream
   e0b9a42735f2672ca2764cfbea6e55a81098d5ba
   191941692a3d1b6a9614502b279be062926b70f5)
2, insmod new kmod
3, enable crash_kexec_post_notifiers,
  # echo 1 > /sys/module/kernel/parameters/crash_kexec_post_notifiers
4, trigger kernel panic
  # echo 1 > /proc/sys/kernel/sysrq
  # echo c > /proc/sysrq-trigger

Host side:
1, build new qemu with pvpanic patches (with commit from upstream
   600d7b47e8f5085919fd1d1157f25950ea8dbc11
   7dc58deea79a343ac3adc5cadb97215086054c86)
2, build libvirt with this patch
3, handle lifecycle event and trigger guest side panic
  # virsh event stretch --event lifecycle
  event 'lifecycle' for domain stretch: Crashed Crashloaded

      util: consolidate on one free callback for hash data · bc7e7291
      由 Daniel P. Berrangé 提交于 
      This previous commit introduced a simpler free callback for
hash data with only 1 arg, the value to free:

  commit 49288fac
  Author: Peter Krempa <pkrempa@redhat.com>
  Date:   Wed Oct 9 15:26:37 2019 +0200

    util: hash: Add possibility to use simpler data free function in virHash

It missed two functions in the hash table code which need
to call the alternate data free function, virHashRemoveEntry
and virHashRemoveSet.

After the previous patch though, there is no code that
makes functional use of the 2nd key arg in the data
free function. There is merely one log message that can
be dropped.

We can thus purge the current virHashDataFree callback
entirely, and rename virHashDataFreeSimple to replace
it.

      Drop needless ret variable · 3b4df5d3
      由 Michal Privoznik 提交于 
      In few places we have the following code pattern:

  int ret;
  ... /* @ret is not accessed here */
  ret = f(...);
  return ret;

This pattern can be written less verbose:

  ...
  return f(...);

This patch was generated with following coccinelle spatch:

  @@
  type T;
  constant C;
  expression f;
  identifier ret;
  @@
  -T ret = C;
   ... when != ret
  -ret = f;
  -return ret;
  +return f;

Afterwards I needed to fix a few places, e.g. comment in
virDomainNetIPParseXML() was removed too because coccinelle
thinks it refers to @ret while in fact it doesn't. Also in few
places it replaced @ret declaration with a few spaces instead of
removing the line. But nothing terribly wrong.
