First, u want the operation reverse that of deletion - in kernel
module format....then look at delete_inode at the VFS first:
void generic_delete_inode(struct inode *inode)
{
const struct super_operations *op = inode->i_sb->s_op;
list_del_init(&inode->i_list);
list_del_init(&inode->i_sb_list);
for the above two, the operation is irreversible. So whatever
originally there is not recoverable.
security_inode_delete(inode);
if (op->delete_inode) {
void (*delete)(struct inode *) = op->delete_inode;
The above means that if it is ext3, then ext3_delete_inode() will be called.
if (!is_bad_inode(inode))
DQUOT_INIT(inode);
/* Filesystems implementing their own
* s_op->delete_inode are required to call
* truncate_inode_pages and clear_inode()
* internally */
delete(inode);===> this will get mapped to
ext3_delete_inode(), and look at that function in ext3, and see how u
can reverse it.
All the above operation is just for ONE inode. Now u need to find
the code that enumerate through ALL the inodes in the ext3
filesystem.....
