rcu_read_lock_bh_held - might we be in RCU-bh read-side critical section?

int rcu_read_lock_bh_held(void);
ARGUMENTS
void

DESCRIPTION
Check for bottom half being disabled, which covers both the CONFIG_PROVE_RCU and not cases. Note that if someone uses rcu_read_lock_bh, but
then later enables BH, lockdep (if enabled) will show the situation.
Check debug_lockdep_rcu_enabled to prevent false positives during boot.
