This is a prerelease +of 3.0, and so backwards compatibility with older versions (1.x, 2.x) +is not supported, and mksquashfs will not append to filesystems. + +The kernel code is for linux 2.6.x and should work on all recent +versions of the 2.6 kernel. The kernel files should be applied to +an existing Squashfs 2.2-r2 patched kernel, the files replace the +Squashfs files, keeping the necessary Squashfs patches in the other +kernel files. + +Squashfs 3.0 is a major improvement to Squashfs. The following +improvements have been made. + + 1. Filesystems are no longer limited to 4 GB. In + theory 2^64 or 4 exabytes is now supported. + + 2. Files are no longer limited to 4 GB. In theory the maximum + file size is 4 exabytes. + + 3. Metadata (inode table and directory tables) are no longer + restricted to 16 Mbytes. + + 4. Hardlinks are now suppported. + + 5. Nlink counts are now supported. + + 6. Readdir now returns '.' and '..' entries. + + 7. Inode numbers are now stored within the inode rather than being + computed from inode location on disk (this is not so much an + improvement, but a change forced by the previously listed + improvements). |
