From b348c262cc6d820a43b1453bc7d745c21619f8aa Mon Sep 17 00:00:00 2001 From: Vladimir Sementsov-Ogievskiy Date: Wed, 28 Jun 2017 15:05:02 +0300 Subject: specs/qcow2: do not use wording 'bitmap header' A bitmap directory entry is sometimes called a 'bitmap header'. This patch leaves only one name - 'bitmap directory entry'. The name 'bitmap header' creates misunderstandings with 'qcow2 header' and 'qcow2 bitmap header extension' (which is extension of qcow2 header) Signed-off-by: Vladimir Sementsov-Ogievskiy Reviewed-by: Eric Blake Reviewed-by: John Snow Message-id: 20170628120530.31251-3-vsementsov@virtuozzo.com Signed-off-by: Max Reitz --- docs/interop/qcow2.txt | 5 ++--- 1 file changed, 2 insertions(+), 3 deletions(-) (limited to 'docs/interop/qcow2.txt') diff --git a/docs/interop/qcow2.txt b/docs/interop/qcow2.txt index aee3553a4f..d7fdb1fee3 100644 --- a/docs/interop/qcow2.txt +++ b/docs/interop/qcow2.txt @@ -203,7 +203,7 @@ The fields of the bitmaps extension are: 8 - 15: bitmap_directory_size Size of the bitmap directory in bytes.
