For that you'd need to find people that were around at SGI in the 90s.. Note that we already removed it briefly in 2008, but unlike my patch that didn't keep the padding so broken log recovery. relevant xfs-import commits: Commit that adds the di_format values: c049a3e8d776a76a1ba3adaf168a406a8ee52172 then various commits in early development add UUID inode format bits, but none seems to actually ever generate it. 1st removal with minor comments on the history: 415c805b441845dfc2be7d887f995ea8875358e9 Revert of the above: 4ddd5953fad77a14f665fefa06899ef9f388b134 -- To unsubscribe from this list: send the line "unsubscribe linux-xfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
