For completeness, the behavior in question: $ cat T.litmus C T {} P0(spinlock_t *x) { int r0; spin_lock(x); spin_unlock(x); r0 = spin_is_locked(x); } $ herd7 -conf linux-kernel.cfg T.litmus Test T Required States 0 Ok Witnesses Positive: 0 Negative: 0 Condition forall (true) Observation T Never 0 0 Time T 0.00 Hash=6fa204e139ddddf2cb6fa963bad117c0 Haven't been using spin_is_locked for a while... perhaps I'm doing something wrong? (IAC, will have a closer look next week...) Andrea
