I'm currently trying to understand how the ext3 on-disk inode works.
How is it filled ? Read/Written ?
I would say look at the fuctions in ../fs/ext3/. You could do a grep on
the ext3 inode struct and see where its being updated(this would find
loads of places and so I think looking at the functions would be a
better approach).
And you can probably start with inode.c
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).
As of now its a fixed 128 bit data type. So the only way you can squeeze
some data would be to comment some lines that are not important(maybe
like support for HURD OS).
