[QEMU HCI-8.0 PATCH 0/5] vhost-blk change backend setup

[Andrey Zhadchenko <andrey.zhadchenko@virtuozzo.com>]

This series changes vhost-blk backend setup from block node to
a path to the device.
Getting fd from block node was a hack in the first place. It
looked ugly and broke encapsulation.
Change vhost-blk to have it's own property so it opens and owns
the descriptor.

Patches #4 implement auto-resize by watching netlink. The problem
is that we cannot efficiently limit the scope without proper eBPF
setup which needs compilation, map handling, eBPFpriveleges and
so on.
Patch #5 tries to filter all events so we can get only resizes
but limited by BPF size.
Both patches are more like an RFC.

Andrey Zhadchenko (5):
  blk: factor out validation
  vhost-blk: change backend setup
  vhost-blk: add read-only flag
  vhost-blk: watch the device for resize events
  vhost-blk: filter uevents in the kernel
