The patch titled
Publish rcutorture module parameters via sysfs, read-only
has been removed from the -mm tree. Its filename was
publish-rcutorture-module-parameters-via-sysfs-read-only.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: Publish rcutorture module parameters via sysfs, read-only
From: Josh Triplett <josh@xxxxxxxxxxxxxxx>
rcutorture's module parameters currently use permissions of 0, so they
don't show up in /sys/module/rcutorture/parameters. Change the permissions
on all module parameters to world-readable (0444).
rcutorture does all of its initialization and thread startup when loaded
and relies on the parameters not changing during execution, so they should
not permit writing. However, reading seems fine.
