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 | | fs/gfs2/rgrp.c | 16 +++++++++++++++- | include/uapi/linux/gfs2_ondisk.h | 15 ++++++++++++--- | 2 files changed, 27 insertions(+), 4 deletions(-) | | -- | 2.13.6 Hi, Series ACK Bob Peterson Red Hat File Systems
