[libvirt] [PATCH v3 2/9] New functions for virBitmap
Hu Tao
hutao at cn.fujitsu.com
Thu Sep 13 06:03:20 UTC 2012
In many places we store bitmap info in a chunk of data
(pointed to by a char *), and have redundant codes to
set/unset bits. This patch extends virBitmap, and convert
those codes to use virBitmap in subsequent patches.
