This series adds rcutorture coverage for the RCU priority-boosting "tardy
deboost" issue. The first 3 patches are Paul's and the next 2 are fixes I had
to make to the test, so that another patch series (I haven't posted yet) can
correctly be tested. I am posting just the test patches first in advance, which
can go in independently if we agree on the changes.
Joel Fernandes (2):
rcutorture: tighten boost-WARN to exclude any implicit-reader context
rcutorture: give async deboost mechanisms up to 500us before WARN
Paul E. McKenney (3):
rcutorture: Abstract reader-segment dump into
rcu_torture_dump_read_segs()
rcutorture: Check for immediate deboosting at reader end
rcutorture: Test RCU readers from hardware interrupt handlers
