- While checking the information below using herd7, I've observed some
"strange" behavior with spin_is_locked() (perhaps, unsurprisingly...);
IAC, that's also excluded from this table/submission.
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);
}
Since 0 executions are generated, possibly herd things there's a deadlock.
Could be either a problem with the deadlock definition, or do you need
to initialize the lock somehow?
