Subject: [PATCH 07/10] linux: Consolidate statvfs implementations
Date: Mon,  8 Feb 2021 18:49:33 -0300	[thread overview]
Message-ID: <20210208214936.1502047-8-adhemerval.zanella@linaro.org> (raw)
In-Reply-To: <20210208214936.1502047-1-adhemerval.zanella@linaro.org>

There is no need to handle ENOSYS on fstatfs64 call, required only
for alpha (where is already fallbacks to fstatfs).

Checked on x86_64-linux-gnu.
