H A D | Kconfig | cf1e2289 Mon May 08 14:33:53 CDT 2017 Dan Williams <dan.j.williams@intel.com> device-dax: kill NR_DEV_DAX
There is no point to ask how many device-dax instances the kernel should support. Since we are already using a dynamic major number, just allow the max number of minors by default and be done. This also fixes the fact that the proposed max for the NR_DEV_DAX range was larger than what could be supported by alloc_chrdev_region().
