This patch can ensure that loop devices based on erofs and overlayfs
can't set dio through __loop_update_dio.
So does this mean that you tested the "loop on overlayfs on erofs"
setup and it works?
Yes, I think this has always been able to work normally. But recently we
found that the direct_IO flag will be set incorrectly in the Android apex
scenario, which leads to oops.
With this patch, Android apex can work normally through loop on overlayfs
on erofs using bufferd IO.
