From 696e4219237b4cac48b5145f497f4840bb5e3391 Mon Sep 17 00:00:00 2001 From: Rasmus Villemoes Date: Tue, 30 Oct 2018 15:04:54 -0700 Subject: [PATCH] lib/bitmap.c: remove wrong documentation This promise is violated in a number of places, e.g. already in the second function below this paragraph. Since I don't think anybody relies on this being true, and since actually honouring it would hurt performance and code size in various places, just remove the paragraph.
