That explains where the source of the problem comes from (it's the use

Small correction, the SELECT FOR UPDATE was removed from Nova's
quota-handling code in the Pike release.

Elaboration: the calls to quota reserve/commit/rollback were removed in the Pike release, so with_lockmode('update') is not called for quota operations, even though the reserve/commit/rollback methods are still there for use by old (Ocata) computes during an Ocata => Pike upgrade. Then, the reserve/commit/rollback methods were removed in Queens once no old computes could be calling them.
