[PATCH 0/3] xfs: more verifications!

[Dave Chinner <david@fromorbit.com>]

Hi folks,

This patchset addresses a series of corruptions noticed in an image
provided by Wen Xu. The patches only address detecting corruptions
before they can do damage - it does not address/fix the crash the
image caused but instead prevents the bad information from getting
to the point where it can cause a crash.

The third patch addresses a general btree record validation issue;
we should probably dirve this inwards to each btree implementation
with a ->verify_record() callout, as this patch does not address
all the places that btree records are traversed during searches. It
will catch any attempt to use a bad record that a search lands on,
however.

Comments?

-Dave.
