Subject: [RFC/RFT patch 5/7] posix-timers: Conflate clock MONOTONIC and BOOTTIME
Date: Thu, 01 Mar 2018 17:33:36 +0100	[thread overview]
Message-ID: <20180301165150.315745557@linutronix.de> (raw)
In-Reply-To: 20180301163331.987775783@linutronix.de

[-- Attachment #1: posix-timers--Conflate-clock-MONOTONIC-and-BOOTTIME.patch --]
[-- Type: text/plain, Size: 1880 bytes --]

Now that clock MONOTONIC and BOOTTIME are indentical remove all the special
casing. The user space visible interfaces still support both clocks.
