Subject: [PATCH 01/16] linux: Always define STAT_IS_KERNEL_STAT
Date: Thu, 23 Jul 2020 16:46:26 -0300 [thread overview]
Message-ID: <20200723194641.1949404-2-adhemerval.zanella@linaro.org> (raw)
In-Reply-To: <20200723194641.1949404-1-adhemerval.zanella@linaro.org>
It allows to check for its value instead of its existence.
Checked with a build for all affected ABIS.
