A single rwsem fix.
Side note, this one isn't marked for stable, but I'm hoping stable picks it up just from the "Fixes" tag.
Stable people, we're talking about
a9e9bcb45b15 ("locking/rwsem: Prevent decrement of reader count before increment")
that I just pulled into my tree, and needs to go in 4.9 and later.

Note that it probably is almost entirely impossible to trigger the problem in practice, so it's not like this is a particularly important stable back-port.
I just happened to look at it and go "hmm, it's not _marked_ for stable".

I've addressed a missing a8654596f03 ("locking/rwsem: Enable lock event counting") and queued up a backport for 5.1-4.9.
