Subject: [PATCH] fix fchown fallback on arches without chown(2)
Date: Sat, 27 May 2017 15:20:01 -0500 [thread overview]
Message-ID: <20170527202001.27170-1-samuel@sholland.org> (raw)
The flags argument was missing, causing uninitalized data to be passed
to fchownat(2). The correct value of flags should match the fallback for
chown(3).
