From: Waiman Long <longman@xxxxxxxxxx> redhat/configs: Double MAX_LOCKDEP_ENTRIES for RT debug kernels JIRA: https://issues.redhat.com/browse/RHEL-43425 Due to the fact that RT debug kernel replaces spinlock, rwlock and local_lock to rt_mutex, the number of generated lockdep entries can be increased rather significantly compared with a non-RT debug kernel. So the current MAX_LOCKDEP_ENTRIES of 64k (CONFIG_LOCKDEP_BITS=16) may not be enough for some intensive workloads. Double the MAX_LOCKDEP_ENTRIES of RT debug kernel by increasing CONFIG_LOCKDEP_BITS to 17.
