Hi,

This was briefly discussed in :

Re: [PATCH v5] locking/rwsem: Make handoff bit handling more consistent

Additional testing shows the rwsem hang still exists. It takes a 24hr
fio soak test to show up.

It likely still exists in Linux 5.18.y too. We will be testing that in
the future as time permits.
