debugfs question
Thanks Andreas,
I have a problem
that for the file data I need the fs MetaData is corrupted.
I hope
that because I am using same pre allocate logic all over my FS then I can get
the Maping from other clear state FS file
And read the
data directly from the corrupted FS.
Is that making
sense? *

Thanks,
Yossi

What you
are doing wrong is that you aren't using the debugfs "dump"
command, which
will do what you are trying to do.
