Subject: [PATCH] fix hard-coded disk header chunk size for persistent snapshot
Date: Wed, 12 May 2010 10:29:22 +0900 [thread overview]
Message-ID: <4BEA0472.1060300@jp.fujitsu.com> (raw)
Hi,
This patch fixes hard-coded value for the size of a chunk that includes
disk header for persistent snapshot. It should be changed to existing
macro NUM_SNAPSHOT_HDR_CHUNKS instead of using hard-coded value 1.
Thanks,
Tomohiro Kusumi
