[PATCH 09/23] y2038: stat: avoid 'time_t' in 'struct stat'

From: Arnd Bergmann
Date: Fri Nov 08 2019 - 16:12:29 EST


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.
