0001 What: /sys/devices
0002 Date: February 2006

0004 Description:
0005 The /sys/devices tree contains a snapshot of the
0006 internal state of the kernel device tree. Devices will
0007 be added and removed dynamically as the machine runs,
0008 and between different kernel versions, the layout of the
0009 devices within this tree will change.
0010
0011 Please do not rely on the format of this tree because of
0012 this. If a program wishes to find different things in
0013 the tree, please use the /sys/class structure and rely
0014 on the symlinks there to point to the proper location
0015 within the /sys/devices tree of the individual devices.
0016 Or rely on the uevent messages to notify programs of
0017 devices being added and removed from this tree to find
0018 the location of those devices.
0019
0020 Note that sometimes not all devices along the directory
0021 chain will have emitted uevent messages, so userspace
0022 programs must be able to handle such occurrences.
