Hello,

I'm currently trying to understand how the ext3 on-disk inode works.
How is it filled ? Read/Written ? How add a new attribute to it.
I'll be *very* pleased if I could add a 32-bit field (at least, or better a 64-bits field).
Is thery somebody who have some information for this ? Any help will be greetly appreciated :).


Same question for the ext3 superblock.

Still concerning ext3. Does somebody know the full purpose of the s_uuid field in ext3 super_block ? What its value means ? This field is 128-bits long and I need a filesystem identifier 64-bits long max. An idea where I could find it ?

Thanks in advance

Aurelien
