My new patchset intends to expand on your earlier inode/superblock patches by adding checksums to nearly all metadata objects (directory blocks, htree, extent tree, block/inode bitmaps, extended attributes). It also adds code to e2fsprogs to verify the checksums, and make the necessary adjustments to the on-disk format to add space for checksums. --D > > -Andi > -- > To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in > the body of a message to majordomo@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html
