@T.Tso and J.Axboe
e1333462e3 was not able to compile the 4.19.5 kernel.

Long story, gcc begins to complain of missing elfutils package (it was
installed already). I felt also in an old CONFIG_UNWINDER_ORC bug "Cannot
generate ORC metadata". Compilations begin to fail with a "cannot make
executable" error. As unbelievable it is, the bug was reported recently
(https://lkml.org/lkml/2018/11/5/108).
I'm using dev-libs/elfutils-0.175 and the kernel isn't affected by
https://bugs.gentoo.org/671760

The good news. 4.19.4 kernel with the part to 'block/blk-core.c' of your patch
has compiled 4.19.5. It doesn't show any sign of ext4 corruption.

I'm waiting for the next backup tomorrow.
