| Subject: [PATCH] libgfs2: Add beginnings of a metadata description
| The intent here is to start a framework which will describe the
| GFS/GFS2 metadata in enough detail to be used by the utilities.
| Initially there is little more than names, sizes and offsets of
| the various fields, but I hope to expand on this a bit in future.
| The other thing that I've added, is a simple self-check function.
| Again, I hope that we can build on this base and expand the tests
| as time goes on.
| Currently nothing uses this new infrastructure, but again, in time
| it should be possible to integrate it into the utilities. In the
| mean time I want to make sure it is as complete and correct as
| possible.
| A side effect of this is that every bit of metadata has been
| assigned a unique id. That includes those items which do not
| have the gfs2_meta_header at the start of them, and so don't
| have a type or format number.
