The patch titled
pps: claim parallel port exclusively
has been removed from the -mm tree. Its filename was
pps-claim-parallel-port-exclusively.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/
------------------------------------------------------
Subject: pps: claim parallel port exclusively
From: Alexander Gordeev <lasaine@xxxxxxxxxxxxx>
Both pps_parport and pps_gen_parport are written in a way that they can't
share a port with any other driver. This can result in locking up the
process that loads modules or even the whole kernel if the modules are
compiled in. Use PARPORT_FLAG_EXCL to indicate this.
