xfs: update sb field checks when metadir is turned on

2024-11-05T21:38:46Z

When metadir is enabled, we want to check the two new rtgroups fields, and we don't want to check the old inumbers that are now in the metadir. Signed-off-by: Darrick J. Wong Reviewed-by: Christoph Hellwig

xfs: move the min and max group block numbers to xfs_group

2024-11-05T21:38:44Z

Move the min and max agblock numbers to the generic xfs_group structure so that we can start building validators for extents within an rtgroup. While we're at it, use check_add_overflow for the extent length computation because that has much better overflow checking. Signed-off-by: Darrick J. Wong Reviewed-by: Christoph Hellwig

xfs: make xfs_rtblock_t a segmented address like xfs_fsblock_t

2024-11-05T21:38:44Z

Now that we've finished adding allocation groups to the realtime volume, let's make the file block mapping address (xfs_rtblock_t) a segmented value just like we do on the data device. This means that group number and block number conversions can be done with shifting and masking instead of integer division. While in theory we could continue caching the rgno shift value in m_rgblklog, the fact that we now always use the shift value means that we have an opportunity to increase the redundancy of the rt geometry by storing it in the ondisk superblock and adding more sb verifier code. Extend the sueprblock to store the rgblklog value. Now that we have segmented addresses, set the correct values in m_groups[XG_TYPE_RTG] so that the xfs_group helpers work correctly.

xfs: don't coalesce file mappings that cross rtgroup boundaries in scrub

2024-11-05T21:38:42Z

The bmbt scrubber will combine file mappings if they are mergeable to reduce the number of cross-referencing checks. However, we shouldn't combine mappings that cross rt group boundaries because that will cause verifiers to trip incorrectly. Signed-off-by: Darrick J. Wong Reviewed-by: Christoph Hellwig

xfs: encode the rtsummary in big endian format

2024-11-05T21:38:41Z

Currently, the ondisk realtime summary file counters are accessed in units of 32-bit words. There's no endian translation of the contents of this file, which means that the Bad Things Happen(tm) if you go from (say) x86 to powerpc. Since we have a new feature flag, let's take the opportunity to enforce an endianness on the file. Encode the summary information in big endian format, like most of the rest of the filesystem.
