Date: Tue, 17 Apr 2007 13:01:38 +0200 From: Cornelia Huck <cornelia.huck@...ibm.com> To: Greg K-H <greg@...ah.com>, Frank Pavlic <fpavlic@...ibm.com> Cc: linux-kernel <linux-kernel@...r.kernel.org>, Linux Netdev List <netdev@...r.kernel.org> Subject: [Patch driver tree] qeth: Remove usage of subsys.rwsem Hi, the current driver tree contains the removal of subsys.rwsem. Unfortunately, this breaks qeth. However, it should be no problem to fix the walking of the devices for /proc/qeth: No need to take subsys.rwsem during walking the devices, driver_find_devices() should already suffice.
