58c2ecf20Sopenharmony_ciDescription:	The /sys/dev tree provides a method to look up the sysfs
68c2ecf20Sopenharmony_ci		path for a device using the information returned from
78c2ecf20Sopenharmony_ci		stat(2).  There are two directories, 'block' and 'char',
88c2ecf20Sopenharmony_ci		beneath /sys/dev containing symbolic links with names of
98c2ecf20Sopenharmony_ci		the form "<major>:<minor>".  These links point to the
108c2ecf20Sopenharmony_ci		corresponding sysfs path for the given device.

128c2ecf20Sopenharmony_ci		Example::
138c2ecf20Sopenharmony_ci
148c2ecf20Sopenharmony_ci		  $ readlink /sys/dev/block/8:32
158c2ecf20Sopenharmony_ci		  ../../block/sdc
168c2ecf20Sopenharmony_ci
178c2ecf20Sopenharmony_ci		Entries in /sys/dev/char and /sys/dev/block will be
188c2ecf20Sopenharmony_ci		dynamically created and destroyed as devices enter and
198c2ecf20Sopenharmony_ci		leave the system.
