2eabb7e89b Switched from I/O engine sync to psync because the latter has a slightly lower system call overhead.

81bf548098 - Added command-line option -j, which allows to use fio for measuring 
I/O times instead of dd.
- For asynchronous (buffered) write tests with dd, switched from
  sync-after-every-write to sync-at-end.

b780be7a7b Various improvements: 
- Display a clear warning if the user running this script does not have
  sufficient privileges to drop the VM caches.
- Made sure that header and data columns are aligned if dd reports an
  error, e.g. when trying to perform direct I/O on a device that does
  not support direct I/O.
- Made sure that header and data columns are aligned when running a
  read-only test (-r).

6947c6168e Added command-line option -t, which allows to drop the caches of the target too. Added dd flag conv=notrunc to write performance tests, which makes running blockdev-perftest on files instead of devices a lot easier.

ed81fdc037 Fixed a bug that was introduced in the previous revision: the script entered an infinite loop when the size specified through -s was smaller than 64MB.

5c4a41b656 - Added command-line option -i.

5687a49e80 Changes: 
- Added command-line options -a, -d, -n and -s.
- If the syntax of the command-line options is incorrect, a usage text
  is displayed.
- Bug fix: log2_io_size is now honored even if the target device is larger
  than the specified size.
