1 | What: /sys/dev |
2 | Date: April 2008 | |
3 | KernelVersion: 2.6.26 | |
4 | Contact: Dan Williams <dan.j.williams@intel.com> | |
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. | |
