Subject: [PATCH 2/7] tty: termios: Reserve space for VSTATUS in .c_cc
Date: Wed, 5 Jun 2019 11:19:01 +0300 [thread overview]
Message-ID: <20190605081906.28938-3-ar@cs.msu.ru> (raw)
In-Reply-To: <20190605081906.28938-1-ar@cs.msu.ru>
There was no architecture we had to increase NCCS on,
so the size of struct termios did not change.
Signed-off-by: Arseny Maslennikov <ar@cs.msu.ru>
