I have confirmed that that commit fixes the problem. I tested using Ubuntu's mainline patches on top of the following two commits. I first tested with https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/log/?h=v4.19-rc3&qt=range&q=2c205dd3981f . It had the problem. I then tested with https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?h=v4.19-rc3&id=368982cd7d1bd41cd39049c794990aca3770db44 . It did not have the problem. So, 368982cd7d1b does indeed fix the problem I am facing.
