[PATCH tip/core/rcu 0/3] Torture-test update for v4.15

[Paul E. McKenney]

Hello!

This series contains torture-test updates:

1.	Add interrupt-disable capability to stall-warning tests.

2.	Dump writer stack if rcutorture writer kthread is stalled.

3.	Provide TMPDIR environment variable to specify temporary
	directory in order to run rcutorture on oddly configured
	systems.

							Thanx, Paul
