| H A D | mmp.c | 65 * mmp_delay field is a decaying average of the amount of time between
106 * within (multihost_interval + mmp_delay) because multihost_interval is
107 * enough time for a write to be attempted to each leaf vdev, and mmp_delay
336 * much longer, intervals. The mmp_delay captures long periods between
340 * The mmp_delay is usually calculated as a decaying average, but if the latest
345 * the mmp_delay could become very small. Since those short delays depend on
346 * activity we cannot count on, we never allow mmp_delay to get lower than rate
350 * mmp_delay, we need to update it so the next write reflects the longer delay.
