Changes since version 3.397:
Revision 3.408
Bug fix for clobbering of buffer. "tfile" needed to be bigger, as its
address was loaded into filearray[] and then that was overwritten
by the mfflag causing parsed names to get loaded.
Revision 3.407
Work around for cache_line_size suddenly becoming zero and breaking fetchit()
Revision 3.406
Increase buffer size for configuration lines. They might be 700 chars long.
Revision 3.405
Reduce CPU consumption in the op_rate control mechanism.
Revision 3.404
Fix type-oh in usage message.
Revision 3.403
Add -+W to permit chid_skew. This permits adding files, and continuing
the proper sharing/dedup within each quadrant, within same seed group
and with previously existing files that were created with a different
number of threads.
Revision 3.402
Mods for DragonFly support.
Revision 3.401
bug fix for re-write rec.
Revision 3.398
Adding thread_read_test and thread_write_test.
The update from version 3.308 to 3.397 broke DragonFly 11 days after I
fixed it due to missing a macro change. An integer redeclaration was
also removed.
It appears that the authors of Iozone tried to add DragonFly support without
actually building it. The configuration was broken, and the iozone.c
was uncompilable. With the two modified patches, it will compile now, and a
quick check using "iozone -a" seemed to work as expected.
No PKGREVISION bump necessary.
pkgsrc changes:
- add 'tee' to USE_TOOLS.
- support an optional build with threads support and also support this in the
'benchmark' target.

Fixes PR 35265, although I did not use the patch provided therein.
* Change the default pattern. Samba is trying to cheat by
special casing IOZONE.tmp, and the pattern of 0xA5.
* Make the default pattern random, and based on Iozone version.
This is to prevent the hack from Richard Sharpe (in Samba)
from special casing Iozone, and lying to the user.
* bug fix in pattern gen.
* Add -+Z old data set mode.
* Add -+X constant data for short circuit testing only.
* Multi-node changes for new options. (-+Z and -+X)
* Add -+K flag for Sony.
* Move -+K outside of Windows only.
* Simplify percentage calculation
* Add error checking for -f and -F in the wrong modes.
* Bug fix for pbuffer allocation on remote clients.
* Check for max_rec_size when using ranges. -r -r -r
* Fix for Debian user bug. -r 1m -n 1m -g 2m gave bogus error.
* Bug fix for -k used in conjunction with -t and content validation.

I have patched the source however, to allow use of the pread/prwite
tests, via the -E extension mode. Also, the benchmark target has been fixed.
