Fio is an I/O testing tool that will spawn a number of threads or
processes doing a particular type of I/O action as specified by
the user. Fio can be driven by a 'job file' describing the I/O
load one wants to simulate.

o Fix terse output with description set
Feature safe: yes
Update to version 2.0.4.
Changes since 2.0 include:
o Fix segfault with net io engine and no file/hostname given.
o Fix net engine client read server write bug.
o Fix early termination of runs caused by ramp_time > runtime
o Implement zoned random I/O testing support
o Fix thread hang when using async engines (libaio,etc.) when too low of a iops
rate...
o Make random map allocation more resilient
o Fail if we can't satisfy the minimum block size
o Enable completion latency stat collection on verify
