There are some ABI documents that, while they don't generate any warnings, they have issues when parsed by get_abi.pl script on its output result. Address them, in order to provide a clean output.

Description: Device DAX is the device-centric analogue of Filesystem
|
|
DAX (CONFIG_FS_DAX). It allows memory ranges to be
|
|
allocated and mapped without need of an intervening file
|
|
system. Device DAX is strict, precise and predictable.
|
|
Specifically this interface:
|
|
|
|
1. Guarantees fault granularity with respect to a given
|
|
page size (pte, pmd, or pud) set at configuration time.
|
|
|
|
2. Enforces deterministic behavior by being strict about
|
|
what fault scenarios are supported.
|
|
|
|
The /sys/class/dax/ interface enumerates all the
|
|
device-dax instances in the system. The ABI is
|
|
deprecated and will be removed after 2020. It is
|
|
replaced with the DAX bus interface /sys/bus/dax/ where
|
|
device-dax instances can be found under
|
|
/sys/bus/dax/devices/
