The patch titled
ieee1394: sbp2: recheck node generation in sbp2_update
has been removed from the -mm tree. Its filename is
ieee1394-sbp2-recheck-node-generation-in-sbp2_update.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: ieee1394: sbp2: recheck node generation in sbp2_update
From: Stefan Richter <stefanr@xxxxxxxxxxxxxxxxx>
While sbp2_update() is doing its duties after a bus reset, another reset could
happen. Don't accept new requests until the next undisturbed sbp2_update() or
until sbp2_remove().
