Hi, I'm hoping this rings a bell with an mm developer:

    https://bugzilla.kernel.org/show_bug.cgi?id=45621

It looks like the user is reporting a OOPS which was caused by the
inode's mapping->page_tree having gotten corrupted.  The call stack
was from a write system call while the system was undergoing heavy
I/O, on a v3.4.7 kernel.

If someone could take a quick look at this, I'd really appreciate it.
Thanks!!

                        - Ted
