Subject: [PATCH v2 06/12] nfsd: pass a 64-bit guardtime to nfsd_setattr()
Date: Fri, 13 Dec 2019 15:10:40 +0100	[thread overview]
Message-ID: <20191213141046.1770441-7-arnd@arndb.de> (raw)
In-Reply-To: <20191213141046.1770441-1-arnd@arndb.de>

Guardtime handling in nfs3 differs between 32-bit and 64-bit
architectures, and uses the deprecated time_t type.

Change it to using time64_t, which behaves the same way on
64-bit and 32-bit architectures, treating the number as an
unsigned 32-bit entity with a range of year 1970 to 2106
consistently, and avoiding the y2038 overflow.

Signed-off-by: Arnd Bergmann <arnd@arndb.de>
