Name
rcu_read_lock_bh_held —
might we be in RCU-bh read-side critical section?
Synopsis
int fsfuncrcu_read_lock_bh_held ( | 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.
