Hello!
The following series improves testing of SRCU-fast and SRCU up/down,
deprecates SRCU-lite, enables torture.sh to skip non-debug testing,
and adds testing for Rust's RCU bindings. The Rust RCU patch is very
much in RFC state, but I am posting it anyway for wider exposure.
1. Make srcu_lockdep.sh check kernel Kconfig.
2. Make srcu_lockdep.sh check reader-conflict handling.
3. Split out beginning and end from rcu_torture_one_read().
4. Make torture.sh --do-rt use CONFIG_PREEMPT_RT.
5. Add tests for SRCU up/down reader primitives.
6. Pull rcu_torture_updown() loop body into new function.
7. Comment invocations of tick_dep_set_task().
8. Complain if an ->up_read() is delayed more than 10 seconds.
9. Check for ->up_read() without matching ->down_read().
10. Deprecate srcu_read_lock_lite() and srcu_read_unlock_lite().
11. Add --do-{,no-}normal to torture.sh.
12. Add testing of RCU's Rust bindings to torture.sh. (RFC)
Changes since v1:
o Apply Z Qiang feedback.
o Add SRCU-lite deprecation, torture.sh --do-{,no-}normal, and
testing of RCU's Rust bindings.
