From be24c7140cf9212de2a00b855939d049d7cb7554 Mon Sep 17 00:00:00 2001 From: Vladimir Sementsov-Ogievskiy Date: Wed, 5 Feb 2020 14:20:33 +0300 Subject: [PATCH] hbitmap: move hbitmap_iter_next_word to hbitmap.c The function is definitely internal (it's not used by third party and it has complicated interface). Move it to .c file.
