* EXECUTIVE SUMMARY
*
*
* FIO_IO_U_PLAT_GROUP_NR and FIO_IO_U_PLAT_BITS determine the maximum
* range being tracked for latency samples. The maximum value tracked
- * accurately will be 2^(GROUP_NR + PLAT_BITS -1) microseconds.
+ * accurately will be 2^(GROUP_NR + PLAT_BITS - 1) nanoseconds.
*
* FIO_IO_U_PLAT_GROUP_NR and FIO_IO_U_PLAT_BITS determine the memory
* requirement of storing those aggregate counts. The memory used will
*
* DETAILS
*
- * 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,
* 3 8 2 [256,511] 64

+ * 28 33 27 [8589934592,+inf]** 64
*
* * Special cases: when n < (M-1) or when n == (M-1), in both cases,
* the value cannot be rounded off. Use all bits of the sample as
* index.
*
