From 2afe27c718b669b551895595873611ac39cc31e3 Mon Sep 17 00:00:00 2001 From: Yury Norov Date: Thu, 16 Apr 2015 12:44:00 -0700 Subject: lib/bitmap.c: bitmap_[empty,full]: remove code duplication bitmap_empty() has its own implementation. But it's clearly as simple as: find_first_bit(src, nbits) == nbits The same is true for 'bitmap_full'.
