--- Comment #9 from Jim Faulkner <jfaulkne@....neu.edu> ---
I ran dumpe2fs -h followed by sync a few times, but was not able to trigger the
bug, nor did the dumpe2fs output differ between syncs.

umount did trigger the bug, however, and the dumpe2fs output was different
after the umount.

After triggering the bug, I was able to capture the debugfs output of one of
the listed inodes.
