Okay, tried the patch now, applied upon:
Linux 4.12.0-trunk-amd64 #1 SMP Debian 4.12.2-1~exp1 (2017-07-18) x86_64 GNU/Linux
(that is the Debian source package, with all their further patches and
their kernel config).

with the parameters at their defaults:
# sysctl vm.dirty_bytes
vm.dirty_bytes = 0
# sysctl vm.dirty_background_bytes
vm.dirty_background_bytes = 0



Tried copying the whole image three times (before I haven had a single
copy of the whole image with at least one error, so that should be
"proof" enough that it fixes the isse) upon the btrfs fs,... no errors
this time...

Looks good :-)


I assume you'll take care to get that patch into stable kernels?
Is this patch alone enough to recommend the Debian maintainers to
include it into their 4.9 long term stable kernels?

And would you recommend this as an "urgent" fix?


Cheers,
Chris.
