| |
Currently, and file handle with a bad inode number in it can cause ext2 to go to readonly (as it looks like a corrupted filesystem) and could allow remote access to ext3 special files like the journal.
These patches give ext2/3 their own get_dentry method which checks the inode number early before other bits of the code can be freaked out by it.
These are revised versions of earlier patches. Rather than exporting export_iget, we open code it and simplify it slightly. This avoids and extra module dependancy.
