Subject: [PATCH tip/core/rcu 0/5] Pre-gp_seq torture-test changes for v4.19

Hello!

The following changes to torture-testing come before the infamous ->gp_seq
conversion:

1.	Use a single build directory for torture scenarios (currently
	there is one directory for each build within a given batch, which
	makes no sense given that all of these builds are serialized).

2.	Remove obsolete TREE08-T.boot file.  Use of the shiny new
	"--bootargs rcutree.rcu_fanout_exact=1" makes use of a separate
	file unnecesary.

3.	Make kvm-find-errors.sh find close calls as well as the usual
	hard errors.

4.	Make online/offline messages appear only for verbose=2.  This
	change is necessitated by the ability to make CPU-hotplug operations
	happen much more frequently than in the past.

5.	Keep old-school dmesg format while Joe Perches is changing the
	default format.  Later, rcutorture can move to the new format
	and at the same time update the analysis scripts.  (As opposed
	to having the analysis scripts just suddenly break when Joe's
	changes hit mainline.)

							Thanx, Paul
