+ * Aggregate clat samples to report percentile(s) of them.
+ *
+ * EXECUTIVE SUMMARY
+ *
+ * FIO_IO_U_PLAT_BITS determines the maximum statistical error on the
+ * value of resulting percentiles. The error will be approximately
+ * 1/2^(FIO_IO_U_PLAT_BITS+1) of the value.
+ *
+ * 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.
+ *
+ * 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
+ * be (FIO_IO_U_PLAT_GROUP_NR * 2^FIO_IO_U_PLAT_BITS) * sizeof(int)
+ * bytes.
+ *
+ * FIO_IO_U_PLAT_NR is the total number of buckets.
+ *
+ * DETAILS
+ *
+ * Suppose the clat 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,
+ * and can be avoided if an approximation is acceptable.
+ *
+ * One such method is to let the range of the bucket to be greater
+ * than one. This method has low accuracy when the value is small. For
+ * example, let the buckets be {[0,99],[100,199],...,[900,999]}, and
+ * the represented value of each bucket be the mean of the range. Then
+ * a value 0 has an round-off error of 49.5. To improve on this, we
+ * use buckets with non-uniform ranges, while bounding the error of
+ * each bucket within a ratio of the sample value. A simple example
+ * would be when error_bound = 0.005, buckets are {
+ * {[0],[1],...,[99]}, {[100,101],[102,103],...,[198,199]},..,
+ * {[900,909],[910,919]...} }. The total range is partitioned into
+ * groups with different ranges, then buckets with uniform ranges. An
+ * upper bound of the error is (range_of_bucket/2)/value_of_bucket
+ *
+ * For better efficiency, we implement this using base two. We group
+ * samples by their Most Significant Bit (MSB), extract the next M bit
+ * of them as an index within the group, and discard the rest of the
+ * bits.
+ *
+ * E.g., assume a sample 'x' whose MSB is bit n (starting from bit 0),
+ * and use M bit for indexing
+ *
+ * | n | M bits | bit (n-M-1) ... bit 0 |
+ *
+ * Because x is at least 2^n, and bit 0 to bit (n-M-1) is at most
+ * (2^(n-M) - 1), discarding bit 0 to (n-M-1) makes the round-off
+ * error
+ *
+ * 2^(n-M)-1 2^(n-M) 1
+ * e <= --------- <= ------- = ---
+ * 2^n 2^n 2^M
+ *
+ * Furthermore, we use "mean" of the range to represent the bucket,
+ * the error e can be lowered by half to 1 / 2^(M+1). By using M bits
+ * as the index, each group must contains 2^M buckets.
+ *
+ * E.g. Let M (FIO_IO_U_PLAT_BITS) be 6
+ * Error bound is 1/2^(6+1) = 0.0078125 (< 1%)
+ *
+ * Group MSB #discarded range of #buckets
+ * error_bits value
+ * ----------------------------------------------------------------
+ * 0* 0~5 0 [0,63] 64
+ * 1* 6 0 [64,127] 64
+ * 2 7 1 [128,255] 64
+ * 3 8 2 [256,511] 64
+ * 4 9 3 [512,1023] 64
+ * ... ... ... [...,...] ...
+ * 18 23 17 [8838608,+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.
+ *
+ * ** If a sample's MSB is greater than 23, it will be counted as 23.
