Description

Yuri reported three smithis stuck in kdb. kdb was misconfigured so I couldn't get anything reliable out of it (not even a partial stack trace), but I am fairly certain it was one of the BUG_ONs in ceph_readdir(). It was the same BUG_ON in all three instances. I did some more poking today and I think it was

BUG_ON(rde->offset < ctx->pos);

on line 501 - at least that's where I'd start my investigation.
