The patch titled
jsm: Remove further unneeded crud
has been removed from the -mm tree. Its filename was
jsm-remove-further-unneeded-crud.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: jsm: Remove further unneeded crud
From: Alan Cox <alan@xxxxxxxxxxxxxxxxxxx>
Remove some remaining vestiges of the old hacks jsm had to work around the old
tty buffering. With the new tty buffering it simply doesn't matter any more.
