[Cluster-devel] [PATCH v2 0/3] gfs2: Add new resource group header fields

[Bob Peterson]

----- Original Message -----
| These patches add new fields to struct gfs2_rgrp. The intention is to improve
| fsck performance and error checking while reducing reliance on the rindex to
| be read in order to scan through the resource groups in tools such as
| fsck.gfs2. This is part of a wider goal to obsolete gfs2's metafs, hence the
| duplication of fields from the rindex. In testing performance, these patches
| carry very little-to-no overhead.
| 
| This posting will be followed by a patch set for gfs2-utils to make use of
| the new fields, and set and check them enough for testing purposes.
| 
| v2: fixed cpu_to_be64/32 typos and made sure rg_skip of the last rgrp is
| zeroed
| 
| Andrew Price (3):
|   gfs2: Add a next-resource-group pointer to resource groups
|   gfs2: Add rindex fields to rgrp headers
|   gfs2: Add a crc field to resource group headers
