Hello, Sami Liedes reported a problem that when a accessing a corrupted filesystem the system deadlocks. The culprit is that the corruption has created a (self-) loop in the directory hierarchy and thus we deadlock when trying to lock i_mutex twice. This patch set attempts at fixing the problem since it seems relatively straightforward. We teach d_splice_alias() to fail when it would add the second connected alias to a directory inode and then handle the failure in filesystems. So far I've taugh ext? filesystems to handle the failure properly but other filesystems should be similarly trivial. Just I'd like to hear whether people agree to the general idea of the fix first.
