Per "ACPI 6.1 Section 9.20.3" NVDIMM devices, children of the ACPI0012 NVDIMM Root device, can receive health event notifications. Given that these devices are precluded from registering a notification handler via acpi_driver.acpi_device_ops (due to no _HID), we use acpi_install_notify_handler() directly. The registered handler, acpi_nvdimm_notify(), triggers a poll(2) event on the nmemX/nfit/flags sysfs attribute when a health event notification is received. Cc: Rafael J.
