git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm Pull libnvdimm fixes from Dan Williams: "A collection of locking and async operations fixes for v5.3-rc2. These had been soaking in a branch targeting the merge window, but missed due to a regression hunt. This fixed up version has otherwise been in -next this past week with no reported issues. In order to gain confidence in the locking changes the pull also includes a debug / instrumentation patch to enable lockdep coverage for libnvdimm subsystem operations that depend on the device_lock for exclusion. As mentioned in the changelog it is a hack, but it works and documents the locking expectations of the sub-system in a way that others can use lockdep to verify. The driver core touches got an ack from Greg. Summary: - Fix duplicate device_unregister() calls (multiple threads competing to do unregister work when scheduling device removal from a sysfs attribute of the self-same device). - Fix badblocks registration order bug. Ensure region badblocks are initialized in advance of namespace registration. - Fix a deadlock between the bus lock and probe operations. - Export device-core infrastructure to coordinate async operations via the device ->dead state. - Add device-core infrastructure to validate device_lock() usage with lockdep" * tag 'libnvdimm-fixes-5.3-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: driver-core, libnvdimm: Let device subsystems add local lockdep coverage libnvdimm/bus: Fix wait_nvdimm_bus_probe_idle() ABBA deadlock libnvdimm/bus: Stop holding nvdimm_bus_list_mutex over __nd_ioctl() libnvdimm/bus: Prepare the nd_ioctl() path to be re-entrant libnvdimm/region: Register badblocks before namespaces libnvdimm/bus: Prevent duplicate device_unregister() calls drivers/base: Introduce kill_device()
