Give or take. There were quite a few related bugs, so some or all of
the following commits might also have helped:

cbe0d8d91415c rcu-tasks: Wait for trc_read_check_handler() IPIs
18f08e758f34e rcu-tasks: Add trc_inspect_reader() checks for exiting critical section
46aa886c483f5 rcu-tasks: Fix IPI failure handling in trc_wait_for_one_reader

Quibbles aside, it is nice to get an automated email about having fixed
a bug as opposed to having added one. ;-)

Thanx, Paul
