Hi all, This patchset adds support in e2fsprogs for attaching crc32c checksums to most of the ext4 metadata objects. A full design document is on the ext4 wiki[1]. Please see the cover letter for the kernel patches for a more thorough summary of this work. Please have a look at the design document and patches, and please feel free to suggest any changes. v2: Checksum the MMP block, store the checksum type in the superblock, include the inode generation in file checksums, and finally solve the problem of limited space in block groups by splitting the checksum into two halves. This patchset has been tested on 3.1.0-rc9 on x64, i386, ppc64, and ppc32. The patches seems to work fine on all four platforms. --D [1] https://ext4.wiki.kernel.org/index.php/Ext4_Metadata_Checksums -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
