Subject: [PATCH 1/4] timekeeping: export do_adjtimex() to modules
Date: Mon,  2 Jan 2017 20:41:11 +0100	[thread overview]
Message-ID: <20170102194114.657-2-vkuznets@redhat.com> (raw)
In-Reply-To: <20170102194114.657-1-vkuznets@redhat.com>

While do_adjtimex() is available to userspace via adjtimex syscall it is
not available to modules which may want to implement in-kernel 'NTP
clients'. Hyper-V hv_utils is going to be the first one.
