| 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. |
