Re: extX features

["arshad hussain" <arshad.super@xxxxxxxxx>]

In above I could not understand what is meant by OS supported ???
Isn't for a filesystem the features are filesystem specific. or OS
here means the VFS layer ???

IMHO ... The book is speaking generally. For example we can mount
ext3 image as ext2 if we do not have ext3 module and loose out
on journalling. I guess it speaking about the whole FS supported by OS.

How can an OS support  or not support
B-trees or journalling, it has to be filesystem dependant......isn't
it ?

I guess the auther got B-tree here as an example wrong when he
is discussing ext[X].

Thanks
