*
- * Suppose the clat varies from 0 to 999 (usec), the straightforward
+ * Suppose the lat varies from 0 to 999 (usec), the straightforward
* method is to keep an array of (999 + 1) buckets, in which a counter
* keeps the count of samples which fall in the bucket, e.g.,
* {[0],[1],...,[999]}. However this consumes a huge amount of space,
