History

Jeff Roberson 00ca09449d - Add sysctls at debug.rwlock to control the behavior of the speculative

spinning when readers hold a lock.  This spinning is speculative because,
   unlike the write case, we can not test whether the owners are running.
 - Add speculative read spinning for readers who are blocked by pending
   writers while a read lock is still held.  This allows the thread to
   spin until the write lock succeeds after which it may spin until the
   writer has released the lock.  This prevents excessive context switches
   when readers and writers both hold the lock for brief periods.
