rcutorture: Expand RCUTORTURE_RDR_MASK_[12] to eight bits

Browse source

This commit prepares for testing of multiple SRCU reader flavors by
expanding RCUTORTURE_RDR_MASK_1 and RCUTORTURE_RDR_MASK_2 from a single
bit to eight bits, allowing them to accommodate the return values from
multiple calls to srcu_read_lock*().  This will in turn permit better
testing coverage for these SRCU reader flavors, including testing of
the diagnostics for inproper use of mixed reader flavors.
