5 Description:    The /sys/dev tree provides a method to look up the sysfs
6                 path for a device using the information returned from
7                 stat(2).  There are two directories, 'block' and 'char',
8                 beneath /sys/dev containing symbolic links with names of
9                 the form "<major>:<minor>".  These links point to the
10                 corresponding sysfs path for the given device.
11
12                 Example:
13                 $ readlink /sys/dev/block/8:32
14                 ../../block/sdc
15
16                 Entries in /sys/dev/char and /sys/dev/block will be
17                 dynamically created and destroyed as devices enter and
18                 leave the system.
