Subject: [PATCH 1/9] y2038: libcobalt: Centralize sc_cobalt_clock_gettime syscall
Date: Tue, 1 Jun 2021 11:43:26 +0200 [thread overview]
Message-ID: <20210601094334.774394-2-florian.bezdeka@siemens.com> (raw)
In-Reply-To: <20210601094334.774394-1-florian.bezdeka@siemens.com>
There were two places invoking the sc_cobalt_clock_gettime syscalls
and both places would be updated while introducing y2038 support. To
keep y2038 compatibility as simple as possible the code has been moved
into a simple helper function.
