Subject: [PATCH v2 07/12] nfsd: use time64_t in nfsd_proc_setattr() check
Date: Fri, 13 Dec 2019 15:10:41 +0100 [thread overview]
Message-ID: <20191213141046.1770441-8-arnd@arndb.de> (raw)
In-Reply-To: <20191213141046.1770441-1-arnd@arndb.de>
Change to time64_t and ktime_get_real_seconds() to make the
logic work correctly on 32-bit architectures beyond 2038.
