^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  5) Description:	Device DAX is the device-centric analogue of Filesystem
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  6) 		DAX (CONFIG_FS_DAX).  It allows memory ranges to be
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  7) 		allocated and mapped without need of an intervening file
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  8) 		system.  Device DAX is strict, precise and predictable.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  9) 		Specifically this interface:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) 		1. Guarantees fault granularity with respect to a given
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) 		   page size (pte, pmd, or pud) set at configuration time.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) 		2. Enforces deterministic behavior by being strict about
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) 		   what fault scenarios are supported.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17) 		The /sys/class/dax/ interface enumerates all the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18) 		device-dax instances in the system. The ABI is
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) 		deprecated and will be removed after 2020. It is
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20) 		replaced with the DAX bus interface /sys/bus/dax/ where
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21) 		device-dax instances can be found under
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22) 		/sys/bus/dax/devices/
