-         This option controls how long SRCU delays before entering its
-         loop waiting on SRCU readers.  The purpose of this loop is
-         to avoid the unconditional context-switch penalty that would
-         otherwise be incurred if there was an active SRCU reader,
-         in a manner similar to adaptive locking schemes.  This should
-         be set to be a bit longer than the common-case SRCU read-side
-         critical-section overhead.
