Public bug reported:

I suspect this is a bug in Ext4 and it's handling of sparse files,
specifically recent(ish) additions that allow hole punching with
"fallocate".  I have an application that makes much use of "fallocate"
and whereas it generally works just fine, it seems that under stress the
kernel has problems.
