.BI zone_reset_threshold \fR=\fPfloat
-A number between zero and one that indicates the ratio of logical blocks with
-data to the total number of logical blocks in the test above which zones
-should be reset periodically.
+A number between zero and one that indicates the ratio of written bytes in the
+zones with write pointers in the IO range to the size of the IO range. When
+current ratio is above this ratio, zones are reset periodically as
+\fBzone_reset_frequency\fR specifies. If there are multiple jobs when using this
+option, the IO range for all write jobs has to be the same.

.BI zone_reset_frequency \fR=\fPfloat
A number between zero and one that indicates how often a zone reset should be
OpenBSD and ZFS on Solaris don't support direct I/O. On Windows the synchronous
ioengines don't support direct I/O. Default: false.
.TP
-.BI atomic \fR=\fPbool
-If value is true, attempt to use atomic direct I/O. Atomic writes are
-guaranteed to be stable once acknowledged by the operating system. Only
-Linux supports O_ATOMIC right now.
-.TP
.BI buffered \fR=\fPbool
If value is true, use buffered I/O. This is the opposite of the
\fBdirect\fR option. Defaults to true.

.TP
-.B pmemblk
-Read and write using filesystem DAX to a file on a filesystem

-libpmemblk library.
-.TP
.B dev\-dax
Read and write using device DAX to a persistent memory device (e.g.,
/dev/dax0.0) through the PMDK libpmem library.
