Addition filesystem feature.


It is quite good to have possibility for administrator to put some files together (i.e. close to each other on disk), which will greatly speed up setup, where all them are needed in a short period of time - like boot up or process startup. It can not be solved by delayed allocation, since kernel does not know about relations between files, which in turn results in a need for some kind of on-line disk layout changer (in ext4 it is known as defragmenter), which I was against for in my FS design notes.
