[pve-devel] [PATCH v2 0/6] QEMU backup cancellation fixes

[Stefan Reiter <s.reiter@proxmox.com>]

Some bugfixes for qmp_backup_cancel and create_backup_jobs, that would lead to
VM hangs, wrongly aborted backups or missing/bad error messages.

Now tested with all permutations of
* one vs two disks
* iothread enabled/disabled per disk
and running
    until sudo timeout -s SIGTERM 5s vzdump 100 --storage pbs; do; done
during lunch :)

Sent as seperate patches for review, last patch is for pve-qemu and contains the
changes squashed in with only one new file.

v2:
* fix some more issues (patches 1 and 5)
* fix releasing wrong AioContext after job_cancel_sync
* add patch-of-patches for easier apply

  PVE: fixup: drop CoMutex on error return
  PVE: Introduce generic CoCtxData struct
  PVE: Don't expect complete_cb to be called outside coroutine
  PVE: Don't call job_cancel in coroutines
