Hi,

That commit is in 5.15.6, released December 1, 2021.  And this just now
shows up?  How is this related to 5.15.36-rc1?

Please start a new thread with the authors/reviewers of that commit and
we will be glad to discuss it.

thanks,

greg k-h

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.

Will do.

Have a lore.kernel.org link?  Why not continue it there?

Can you test 5.17.y also as there is no 5.18.y yet :)

I tried and the thread is quiet.
