We have also made the following changes:
[PATCH v10 1/14] qdev: unplug blocker for devices
- updated functions comments for unplug blockers in hw/qdev-core.h
[PATCH v10 4/14] vfio-user: build library
- uses meson build system to build libvfio-user library
- dropped ubuntu CI build
[PATCH v10 5/14] vfio-user: define vfio-user-server object
- updated comments for VfioUserServerProperties in qapi/qom.json
[PATCH v10 6/14] vfio-user: instantiate vfio-user context
- added comments to vfu_object_init_ctx() explaining function contract
[PATCH v10 8/14] vfio-user: run vfio-user context
- vfu_object_ctx_run() asserts that VfuObject->device is not NULL
- added a comment to vfu_object_ctx_run() explaining why
VfuObject->device wouldn't be NULL
Thank you very much!
