kay.sievers@vrfy.org 7efa217db0 [PATCH] add NAME{ignore_remove} attribute
Some broken ide drivers are generating high event traffic, with
add/remove events. With this attribute, it can be specified,
that the node is always available. It may be used in conjunction
with the new DRIVER= match to catch specific kernel device drivers.
