sched: Generalize sleep inside spinlock detection

2011-06-22T22:44:38Z

The sleeping inside spinlock detection is actually used for more general sleeping inside atomic sections debugging: preemption disabled, rcu read side critical sections, interrupts, interrupt disabled, etc... Change the name of the config and its help section to reflect its more general role. Signed-off-by: Frederic Weisbecker Acked-by: Paul E.

sched: Make sleeping inside spinlock detection working in !CONFIG_PREEMPT

2011-06-10T13:16:06Z

Select CONFIG_PREEMPT_COUNT when we enable the sleeping inside spinlock detection, so that the preempt offset gets correctly incremented/decremented from preempt_disable()/preempt_enable(). This makes the preempt count eventually working in !CONFIG_PREEMPT when that debug option is set and thus fixes the detection of explicit preemption disabled sections under such config. Code that sleeps in explicitly preempt disabled section can be finally spotted in non-preemptible kernels. Signed-off-by: Frederic Weisbecker Acked-by: Paul E.

lib: consolidate DEBUG_STACK_USAGE option

2011-05-25T15:39:54Z

Most arches define CONFIG_DEBUG_STACK_USAGE exactly the same way. Move it to lib/Kconfig.debug so each arch doesn't have to define it. This obviously makes the option generic, but that's fine because the config is already used in generic code. It's not obvious to me that sysrq-P actually does anything caution by keeping the most inclusive wording. Signed-off-by: Stephen Boyd Cc: Chris Metcalf Acked-by: David S.

lib: consolidate DEBUG_PER_CPU_MAPS

2011-05-25T15:39:53Z

DEBUG_PER_CPU_MAPS is used in lib/cpumask.c as well as in inlcude/linux/cpumask.h and thus it has outgrown its use within x86 and powerpc alone. Any arch with SMP support may want to get some more debugging, so make this option generic. Signed-off-by: Stephen Boyd Cc: Cc: Ingo Molnar Cc: Thomas Gleixner Cc: "H.
