[openib-general] [PATCH] ib_ucm: remove devfs usage

[Bill Jordan]

Libor,

Here is a patch to remove the devfs usage from ib_ucm.

The udev support already exists, but requires a
rule entry of KERNEL="ucm", NAME="infiniband/%k".
Is there an appropriate place that the udev rules
should be documented?
