computationally expensive. It's not a true random generator, however, though
for IO purposes it's typically good enough. LFSR only works with single block
sizes, not with workloads that use multiple block sizes. If used with such a
-workload, fio may read or write some blocks multiple times.
+workload, fio may read or write some blocks multiple times. The default
+value is tausworthe, unless the required space exceeds 2^32 blocks. If it does,
+then tausworthe64 is selected automatically.
