From: Joe Thornber Date: Wed, 28 Mar 2012 17:41:25 +0000 (+0100) Subject: dm thin metadata: pass correct space map to dm_sm_root_size X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=fef838cc1ac34e599c74888274506d76767f3098;p=deliverable%2Flinux.git dm thin metadata: pass correct space map to dm_sm_root_size Fix a harmless typo. The root is a chunk of data that gets written to the superblock. This data is used to recreate the space map when opening a metadata area. We have two space maps; one tracking space on the metadata device and one of the data device. Both of these use the same format for their root, so this typo was harmless.
