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