		Additionally, the fields Pss_Anon, Pss_File and Pss_Shmem

		are not present in /proc/pid/smaps.  These fields represent

		the sum of the Pss field of each type (anon, file, shmem).

In order to use a diskless system, such as an X-terminal or printer server for

example, it is necessary for the root filesystem to be present on a non-disk

device. This may be an initramfs (see

Documentation/filesystems/ramfs-rootfs-initramfs.txt), a ramdisk (see

Documentation/filesystems/ramfs-rootfs-initramfs.rst), a ramdisk (see

Documentation/admin-guide/initrd.rst) or a filesystem mounted via NFS. The

following text describes on how to use NFS for the root filesystem. For the rest

of this text 'client' means the diskless system, and 'server' means the NFS

Attributes of devices can be exported by a device driver through sysfs.

Please see Documentation/filesystems/sysfs.txt for more information

Please see Documentation/filesystems/sysfs.rst for more information

on how sysfs works.

As explained in Documentation/kobject.txt, device attributes must be

As explained in Documentation/core-api/kobject.rst, device attributes must be

created before the KOBJ_ADD uevent is generated. The only way to realize

that is by defining an attribute group.
