Hi everyone :-)
After updating the kernel to the latest one 4.12 I receive a lot of warnings in
my dmesg but only on my ssd that is a kingston hyperx predator.
No message get logged for my other two traditional HD that are btrfs also.
Warnings show only on boot and not on every boot.
Kernel is now 4.12.5 but I got that till upgrading to 4.12, in 4.11 no warnings.
Just wanted to know if I have to worry about this, scrubs are ok and btrfs
check give me no problems.
Thank you very much.
Mario.

As much as I can tell it's nothing to worry about. (I have thousands
of these warnings.) I don't know why the patch was submitted for 4.13
but not applied to the next 4.12.x , since it looks like a trivial
tiny fix for an annoying problem.

Hi Janos, many thanks for your kind answer!
Yes, I also saw a patch regarding this for 4.13, good to know that it is not a
problem ;-)
Thank you again.
