562306a36Sopenharmony_ciDescription:	The /sys/dev tree provides a method to look up the sysfs
662306a36Sopenharmony_ci		path for a device using the information returned from
762306a36Sopenharmony_ci		stat(2).  There are two directories, 'block' and 'char',
862306a36Sopenharmony_ci		beneath /sys/dev containing symbolic links with names of
962306a36Sopenharmony_ci		the form "<major>:<minor>".  These links point to the
1062306a36Sopenharmony_ci		corresponding sysfs path for the given device.
