ChunkFS

Intro/Background

ChunkFS is about reducing the file system checking (fsck) time. ChunkFS is an idea that Arjan van de Ven and Val Henson came up with in order to avoid the fsck time increase linearly with the disk drive and the metadata on the disk drive increases.

See the reading list for more literature on ChunkFS.

NOTE: No xattrs and xips yet, CONFIG_EXT2_FS_XATTR and CONFIG_EXT2_FS_XIP

should be "no" for clean compile.
