rcu: Remove redundant TREE_PREEMPT_RCU config option

2014-10-29T17:20:05Z

PREEMPT_RCU and TREE_PREEMPT_RCU serve the same function after TINY_PREEMPT_RCU has been removed. This patch removes TREE_PREEMPT_RCU and uses PREEMPT_RCU config option in its place. Signed-off-by: Pranith Kumar Signed-off-by: Paul E. McKenney

rcu: Unify boost and kthread priorities

2014-10-29T17:19:41Z

Rename CONFIG_RCU_BOOST_PRIO to CONFIG_RCU_KTHREAD_PRIO and use this value for both the per-CPU kthreads (rcuc/N) and the rcu boosting threads (rcub/n). Also, create the module_parameter rcutree.kthread_prio to be used on the kernel command line at boot to set a new value (rcutree.kthread_prio=N).

rcu: Remove CONFIG_RCU_CPU_STALL_VERBOSE

2014-10-28T20:48:13Z

The CONFIG_RCU_CPU_STALL_VERBOSE Kconfig parameter causes preemptible RCU's CPU stall warnings to dump out any preempted tasks that are blocking the current RCU grace period. This information is useful, and the default has been CONFIG_RCU_CPU_STALL_VERBOSE=y for some years. It is therefore time for this commit to remove this Kconfig parameter, so that future kernel builds will always act as if CONFIG_RCU_CPU_STALL_VERBOSE=y. Signed-off-by: Paul E. McKenney

rcu: Add step to initrd documentation

2014-09-07T23:24:43Z

This commit tries to get people into the correct directory before creating the initrd directory. Signed-off-by: Paul E. McKenney Reviewed-by: Pranith Kumar

rcu: Remove CONFIG_PROVE_RCU_DELAY

2014-07-09T16:15:31Z

The CONFIG_PROVE_RCU_DELAY Kconfig parameter doesn't appear to be very effective at finding race conditions, so this commit removes it. Signed-off-by: Paul E. McKenney Cc: Andi Kleen [ paulmck: Remove definition and uses as noted by Paul Bolle. ]

rcutorture: Rename TREE_RCU-Kconfig.txt

2014-02-23T17:04:41Z

It used to be that: git ls-files "*Kconfig*" would find all Kconfig files and would only find Kconfig files. This commit renames TREE_RCU-Kconfig.txt to TREE_RCU-kconfig.txt so that this is once again true. Signed-off-by: Paul Bolle Signed-off-by: Paul E. McKenney Reviewed-by: Josh Triplett

rcutorture: Refactor TINY_RCU test cases

2013-12-03T18:11:13Z

The TINY_RCU test cases were first put in place many years ago, and have been incrementally modified rather than being reworked. This commit therefore completes a long-overdue reworking of the TINY_RCU test cases. Signed-off-by: Paul E. McKenney Cc: Greg KH

rcutorture: Add KVM-based test framework

2013-12-03T18:11:10Z

This commit adds the test framework that I used to test RCU under KVM. This consists of a group of scripts and Kconfig fragments. Signed-off-by: Paul E. McKenney Cc: Greg KH
