[Cluster-devel] [PATCH] GFS2: Move generation number into "proper" part of inode



From: Steven Whitehouse <swhiteho redhat com>

This moves the generation number from the gfs2_dinode_host
into the gfs2_inode structure. Eventually the plan is to get
rid of the gfs2_dinode_host structure completely.
