[PATCH 0/4] vhost-user-blk-test: add vhost-user-blk server tests

[Stefan Hajnoczi]

These patches were dropped from Kevin's last block pull request due to a GitLab
CI failure. The old CentOS 7 and opensuse Leap build images lack
memfd_create(2) (introduced in Linux around 2014). The vhost-user-blk server
had a dependency on memfd_create(2) due to VHOST_USER_PROTOCOL_F_INFLIGHT_SHMFD
and qemu-storage-daemon would fail to create a vhost-user-blk export.

Since we have not thought about or tested VHOST_USER_PROTOCOL_F_INFLIGHT_SHMFD
anyway, disable it for now. It can be re-enabled again later when it's needed
for reconnection support.

Coiby Xu (1):
  test: new qTest case to test the vhost-user-blk-server

Stefan Hajnoczi (3):
  block/export: disable VHOST_USER_PROTOCOL_F_INFLIGHT_SHMFD for now
  tests/qtest: add multi-queue test case to vhost-user-blk-test
  vhost-user-blk-test: test discard/write zeroes invalid inputs
