Subject: [Qemu-devel] [PATCH 02/25] specs/qcow2: do not use wording 'bitmap header'
Date: Tue, 30 May 2017 11:17:00 +0300 [thread overview]
Message-ID: <20170530081723.29205-3-vsementsov@virtuozzo.com> (raw)
In-Reply-To: <20170530081723.29205-1-vsementsov@virtuozzo.com>
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)
