A silent data corruption was introduced in v4.10-rc1 with commit 72ecad22d9f198aafee64218512e02ffa7818671 and was fixed in v4.18-rc7 with commit 17d51b10d7773e4618bcac64648f30f12d4078fb. It affects users of O_DIRECT, in our case a KVM virtual machine with drives which use qemu's "cache=none" option.

The other 2 commits has been accepted in 4.14, but 2 are missing, ref: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1796542

Please consider to include them in next release.

I've ended up cherry picking these two into the 4.14 tree.

Thanks Sasha!
