* [Cluster-devel] GFS2 clean up patches @ 2008-11-10 10:30 swhiteho 2008-11-10 10:30 ` [Cluster-devel] [PATCH] GFS2: Move generation number into "proper" part of inode swhiteho 0 siblings, 1 reply; 10+ messages in thread From: swhiteho @ 2008-11-10 10:30 UTC (permalink / raw) To: cluster-devel.redhat.com The following are a bunch of clean up patches for GFS2. In combination they remove a couple of structures which are not required from incore.h, merging the fields into the containing structures. This completes the removal of two of the _host structures which was one of the things promised during the original merge/review process. Also the final patch adds some further information to the debugfs file through which the glock state can be read to aid debugging.

Thats renamed to i_diskflags in order to avoid confusion with the existing inode flags, and moved into the inode proper at a suitable location to avoid creating a "hole". At that point struct gfs2_dinode_host is no longer needed and as promised (quite some time ago!) it can now be removed completely.
