Subject: [PATCH 09/11] y2038: remove struct definition redirects
Date: Thu, 10 Jan 2019 17:22:14 +0000	[thread overview]
Message-ID: <20190110172216.313063-10-arnd@arndb.de> (raw)
In-Reply-To: <20190110172216.313063-1-arnd@arndb.de>

We now use 64-bit time_t on all architectures, so the __kernel_timex,
__kernel_timeval and __kernel_timespec redirects can be removed
after having served their purpose.

This makes it all much less confusing, as the __kernel_* types
now always refer to the same layout based on 64-bit time_t across
all 32-bit and 64-bit architectures.
