These logs are something I've not seen here in my testing. This shows that we are stuck doing an up_write() on root->rwsem in the anon_vma path. It looks like we are contending on the rwsem's sem->wait_lock. I don't have a reproduction of this issue, it will be interesting to examine what is causing the heavy contention
