Hi...
could someone help me with freeing a used ag?
I want to do it inside the kernel and while the fs is mounted. I've
already looked at the code, and it looks to me that freeing the agi of
an ag is the easier part, so i want to start with it. I thought i could
look at each inode of the agi i want to free, but i think i must iterate
over each inode when freeing the used blocks anyway. So i iterate over
each inode (starting with the root inode) and move the inode to a new
one if it is inside the ag which should be freed. The second step is to
look at the inode itself. If the data block is inside the ag it could be
moved outside the ag too.
If i missed something until here, please let me know:-)
My questions are:
1. Is there a facility to iterate over each used inode?
2. how could i easily copy the inode to a free space outside the current
agi (i thought of setting pag.pagf_freeblks, pag.pagf_flcount,
pag.pagf_longest to 0).
3. have i missed something or is there a better way to do it?
Any help is appreciated.
Thank you very much in advance.
Best regards,
Markus Lidel
