Linux kernel 2.6.30 Released with New File Systems Support
Linus Torvalds announced Linux kernel 2.6.30, adding several new filesystems, including the NILFS2 log-structured filesystem. Linux 2.6.30 enhancements include a local caching layer for NFS data, the RDS server cluster communications protocol, the Tomoyo security module, and support for LZMA and BZIP2 compression algorithms. The new NILFS2 treats the whole disk as a consecutive list of blocks (or "log"), and never rewrites blocks. As a result, all modifications and creations are converted into sequential operations, which are said to be faster. Other NILFS2 improvements are said to include the ability to offer a more coherent historical view of operations, called "continuus snapshotting," enabling users to restore files that have been mistakenly destroyed only a few seconds previously. In addition to the NILFS2 system, Linux 2.6.30 adds an EXOFS filesystem designed for object-based storage, and a POHMELFS distributed networking filesystem. Other filesystem enhancem...
