SquashFS Getting Major Performance Enhancements

SquashFS is commonly used by Linux distributions as a compressed read-only file-system commonly used by the Live CD/DVD/USB versions of distributions like Ubuntu, Arch, Fedora, Debian, etc. There's some performance improvements to be merged into the Linux kernel that will make SquashFS even faster. SquashFS decompression can be multiple times faster with these patches.
