What: /sys/dev
|
|
Date: April 2008

KernelVersion: 2.6.26

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.
