rcu: Add RCU_CPU_STALL_VERBOSE to dump detailed per-task information
When RCU detects a grace-period stall, it currently just prints out the PID of any tasks doing the stalling. This patch adds RCU_CPU_STALL_VERBOSE, which enables the more-verbose reporting from sched_show_task(). Suggested-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Paul E.
