Subject: [PATCH v3 01/10] compat: Make compat helpers independent of CONFIG_COMPAT
Date: Mon, 15 Jan 2018 18:18:09 -0800 [thread overview]
Message-ID: <20180116021818.24791-2-deepa.kernel@gmail.com> (raw)
In-Reply-To: <20180116021818.24791-1-deepa.kernel@gmail.com>
Many of the compat time syscalls are also repurposed as 32 bit
native syscalls to provide backward compatibility while adding
new y2038 safe sycalls.
Enabling the helpers makes this possible.
