Hi Ulf,

Thanks for applying.  Although, I saw it got queued to the next merge
window, but I we believe it to be -rc material, since it fixes a hang
in our kernelCI boxes[1], and is preventing us from testing other features
in this box.  Can you consider submitting it to Linus for the next -rc?
it will be much appreciated!

Thanks.
