panic: backing_object 0xdea7b258 was somehow re-referenced during collapse!

[Sepherosa Ziehau <sepherosa@xxxxxxxxx>]

This happens when I stress my local UDP work.  It is not easily
reproducible; it does not happen in the first 12 hours' stressing at
least.

The dump is uploaded to sephe@leaf:crash/execv.tbz

The kernel w/o local patches is at 1a92ebbba565e9b19de3767cd55cf0d2f95c160a

Best Regards,
sephe
