Subject: RHEL8 compatibility
Date: Tue, 10 Sep 2019 22:42:40 +0200
Message-ID: <3256534.Vi1k177MCT@themisto> (raw)

Hello,

The RHEL8 kernel (4.18) contains backported changes that make it act more like
a > 4.7 kernel. As such src/compat/compat.h need to be patched to handle
RHEL8 special case.

We are currently using this patch in RPMFusion EPEL8 branch:

--- a/WireGuard-0.0.20190702/src/compat/compat.h

Could you please define a ISRHEL8 to handle this?
