Subject: [PATCH 14/23] y2038: make ns_to_compat_timeval use __kernel_old_timeval
Date: Fri,  8 Nov 2019 22:12:13 +0100	[thread overview]
Message-ID: <20191108211323.1806194-5-arnd@arndb.de> (raw)
In-Reply-To: <20191108210236.1296047-1-arnd@arndb.de>

This gets us one step closer to removing 'struct timeval' from the
kernel. We still keep __kernel_old_timeval for interfaces that we cannot
fix otherwise, and ns_to_compat_timeval() is provably safe for interfaces
that are legitimate users of __kernel_old_timeval on native kernels,
so this is an obvious change.
