[RFC PATCH v1 00/15] node_dev_udev: use workerpool and improve nodedev events

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 immediate and to be finished before the libvirt nodedev event is issued to keep the API usage reliable. This patch series already contains the patches from a previous patch series "[RFC PATCH v1 0/5] node_device_udev: small improvements" and has still some TODO's included and is sent therefore as a RFC. Boris Fiuczynski (3): nodedev: fix mdev add udev event data handling nodedev: immediate update of active config on udev add nodedev: reset active config data on udev remove event Marc Hartmayer (12): node_device_udev: Set @def to NULL node_device_udev: Remove the timeout if the data is disposed node_device_udev: Test for mdevctlTimeout != -1 node_device_udev: Add comments about locking node_device_udev: Take lock if `driver->privateData` is modified node_device_udev: Add prefix `udev` for udev related data node_device_udev: Inline `udevRemoveOneDevice` node_device_udev: Use `stateShutdownPrepare` and `stateShutdownWait` node_device_udev: Use a worker pool for processing the udev events node_device_udev: Call `nodeDeviceUpdateMediatedDevices` directly node_device_udev: Don't take `mdevctl` lock for querying `mdevctl list` node_device_udev: Make the code easier to read src/node_device/node_device_driver.h | 5 +- src/util/virmdev.h | 4 + src/conf/node_device_conf.c | 10 +- src/node_device/node_device_driver.c | 19 +- src/node_device/node_device_udev.c | 435 ++++++++++++++++++--------- src/test/test_driver.c | 3 +- src/util/virmdev.c | 20 ++ src/libvirt_private.syms | 2 + 8 files changed, 339 insertions(+), 159 deletions(-) base-commit: 4b5cc57ed35dc24d11673dd3f04bfb8073c0340d -- 2.34.1
