drivers/dax/dax.c implements a character device that supports mmap().
While trying to convert it to use the cdev api a unit test started
failing. The test effectively does the following to test that the driver
revokes active mappings when the device is unregistered:
fd = open("/dev/dax0.0", ..
The unit tests crash when hotplug races the previous probe. This race
requires that the loading of the nfit_test module be terminated with
SIGTERM, and the module to be unloaded while the ars scan is still
running.
In contrast to the normal nfit driver, the unit test calls
acpi_nfit_init() twice t
