It seems the patch you mentioned was merged to upstream Linux here:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=71472fa9c52b1da27663c275d416d8654b905f05
and then reverted/removed here:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=896d81fefe5d1919537db2c2150ab6384e4a6610
Do you know if there has been proper/fixed patch after that? has it been merged to upstream Linux kernel already?
Thanks,
