Hey, at least you were willing to dig into it and find a problem!

timers: Fix excessive granularity of new timers after a nohz idle
When a timer base is idle, it is forwarded when a new timer is added to
ensure that granularity does not become excessive. When not idle, the
timer tick is expected to increment the base.
However there is a window after a timer is restarted from nohz, when it
is marked not-idle, and before the timer tick on this CPU, where a timer
may be added on an ancient base that does not get forwarded (beacause
the timer appears not-idle).
This results in excessive granularity. So much so that a 1 jiffy timeout
has blown out to 10s of seconds and triggered the RCU stall warning
detector.
Fix this by always forwarding the base when adding a new timer if it is
more than 1 jiffy behind. Another approach I looked at first was to note
if the base was idle but not yet run or forwarded, however this just
seemed to add more branches and complexity when it seems we can just
cover it with this test.
Also add a comment noting a case where we could get an unexpectedly
large granularity for a timer. I debugged this problem by adding
warnings for such cases, but it seems we can't add them in general due
to this corner case.

https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git locking/core
commit d0541b0fa64b36665d6261079974a26943c75009
Author: Byungchul Park <byungchul.park(a)lge.com>
AuthorDate: Thu Aug 17 17:57:39 2017 +0900

locking/lockdep: Make CONFIG_LOCKDEP_CROSSRELEASE part of CONFIG_PROVE_LOCKING
Crossrelease support added the CONFIG_LOCKDEP_CROSSRELEASE and CONFIG_LOCKDEP_COMPLETE
options. It makes little sense to enable them when PROVE_LOCKING is disabled.
Make them non-interative options and part of PROVE_LOCKING to simplify the UI.
