Subject: [gentoo-dev] [PATCH v2 2/2] linux-info.eclass: Replace bit-shift arithmetic by ver_test
From: Ulrich Müller <ulm () gentoo ! org>
Date: 2021-08-28 5:41:17
Message-ID: 20210828054115.28686-2-ulm () gentoo ! org
[Download RAW message or body]
There are kernel versions like 4.9.280, therefore shifting version
components by 8 bits in kernel_is() may fail.
Signed-off-by: Ulrich Müller <ulm@gentoo.org>
