Comment 2 Vladis Dronov 2017-11-16 13:22:05 UTC
an upstream patch:

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=363b02dab09b3226f3bd1420dad9c72b79a42a76

it was in the upstream since v4.14-rc6, so i believe fedora's kernel rpm is missing it.

Comment 3 Justin M. Forbes 2018-01-29 16:59:11 UTC
This was fixed for Fedora with the 4.13.10 stable updates.
