| What: /sys/dev | |
| Date: April 2008 | |
| KernelVersion: 2.6.26 | |
| Contact: Dan Williams <dan.j.williams@intel.com> | |
| Description: The /sys/dev tree provides a method to look up the sysfs | |
| path for a device using the information returned from | |
| stat(2). There are two directories, 'block' and 'char', | |
| beneath /sys/dev containing symbolic links with names of | |
| the form "<major>:<minor>". These links point to the | |
| corresponding sysfs path for the given device. | |
| Example: | |
| $ readlink /sys/dev/block/8:32 | |
| ../../block/sdc | |
| Entries in /sys/dev/char and /sys/dev/block will be | |
| dynamically created and destroyed as devices enter and | |
| leave the system. | |
