When an udev event occurs for a mediated device (mdev) the mdev config data
requires an update via mdevctl as the udev event does not contain all config
data. This update needs to occur immediately and to be finished before the
libvirt nodedev event is issued to keep the API usage reliable.
Changelog:
RFCv1->v1:
+ removed some of my own s-o-b's that were accidentally inserted in the RFC
+ added r-b's from Boris and Jonathon
+ worked in comments from Boris and Jonathon, but I did not inline
"nodeDeviceDefResetMdevActiveConfig" as I'm not sure whether this improves
the readability
+ reworked patch "[RFC PATCH v1 11/15] node_device_udev: Use
`stateShutdownPrepare` and `stateShutdownWait`"
+ reworked patch "node_device_udev: Use a worker pool for processing events and
emitting nodedev event"
+ added patches:
- node_device_udev: Move responsibility to release `(init|udev)Thread` to `udevEventDataDispose`
- node_device_udev: Fix leak of mdevctlLock, udevThreadCond, and mdevCtlMonitor
- node_device_udev: nodeStateShutdownPrepare: Disconnect the signals explicitly
- node_device_udev: Pass the driver state as parameter in prepartion for the next commit
- node_device_udev: Add support for `g_autoptr` to `udevEventData
- node_device_udev: Pass the `udevEventData` via parameter and use refcounting
Boris Fiuczynski (3):
