Probably this BUG_ON() was wrong. Does this bug occur only by the
specific file?

If so, please do "filefrag -v filename" against that file.

Then, can you try the attached patch? This patch removes the BUG_ON(),
and instead adds printk() for debugging. When the bug occured, it prints
the current cache.

Thanks.
