Subject: [PATCH v2 08/14] linux: Consolidate utimes
Date: Tue,  8 Sep 2020 11:57:32 -0300	[thread overview]
Message-ID: <20200908145738.640039-8-adhemerval.zanella@linaro.org> (raw)
In-Reply-To: <20200908145738.640039-1-adhemerval.zanella@linaro.org>

The generic version does not have time64 support and Linux default
uses utimensat.  With hppa version gone, __ASSUME_UTIMES is not used
anymore.

Checked on x86_64-linux-gnu and i686-linux-gnu (on 5.4 and on 4.15
kernel).
