So in all the cases it seems that struct bfq_group got freed while still being fully linked into various structures. The freeing always happened from blkg_free() called from RCU callback so everything points to the fact that blkg refcount got somehow corrupted (likely someone dropping a ref without taking it). Looking more into this... -- You are receiving this mail because: You are the assignee for the bug.
