Note: While already known devices can be added to the list of devices to be
ignored, there will be no effect on then. However, if such a device
disappears and then reappears, it will then be ignored.
disappears and then reappears, it will then be ignored. To make
known devices go away, you need the "purge" command (see below).
For example,
"echo add 0.0.a000-0.0.accc, 0.0.af00-0.0.afff > /proc/cio_ignore"
will add 0.0.a000-0.0.accc and 0.0.af00-0.0.afff to the list of ignored
You can remove already known but now ignored devices via
"echo purge > /proc/cio_ignore"
All devices ignored but still registered and not online (= not in use)
will be deregistered and thus removed from the system.
The devices can be specified either by bus id (0.x.abcd) or, for 2.4 backward
compatibility, by the device number in hexadecimal (0xabcd or abcd). Device
numbers given as 0xabcd will be interpreted as 0.0.abcd.
