Subject: [PATCH 4/5] ceph: use timespec64 for r_mtime
Date: Wed, 20 Jun 2018 17:50:36 +0200 [thread overview]
Message-ID: <20180620155101.57685-4-arnd@arndb.de> (raw)
In-Reply-To: <20180620155101.57685-1-arnd@arndb.de>
The request mtime field is used all over ceph, and is currently
represented as a 'timespec' structure in Linux. This changes it to
timespec64 to allow times beyond 2038, modifying all users at the
same time.
