Subject: [PATCH 09/23] y2038: stat: avoid 'time_t' in 'struct stat'
Date: Fri, 8 Nov 2019 22:07:29 +0100 [thread overview]
Message-ID: <20191108210824.1534248-9-arnd@arndb.de> (raw)
In-Reply-To: <20191108210236.1296047-1-arnd@arndb.de>
The time_t definition may differ between user space and kernel space,
so replace time_t with an unambiguous 'long' for the mips and sparc.
The same structures also contain 'off_t', which has the same problem,
so replace that as well on those two architectures and powerpc.
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
