From c0b655441804c0edace4f539fb9008b315eb1bd8 Mon Sep 17 00:00:00 2001 From: "Emilio G. Cota" Date: Tue, 27 Sep 2016 17:57:53 -0400 Subject: [PATCH] time: add timemono_since time_mono()'s documentation references time_since(), which is nowhere to be found. A possible fix would be to just remove that stale reference. Instead, this patch adds timemono_since(), which hopefully captures the meaning of the original time_since(). Signed-off-by: Emilio G.
