Hi All,
Somewhere between fio-2.11 and fio-2.11-14-gf031 the bw and iops logs
no longer get written.

See above file sizes of zero for the bw and iops logs. However,
lat/slat/clat are written. Thoughts on which recent commit broke the
functionality? Thanks.
I'll take a look.
Got broken earlier today, with the ramp time fix. The two functions have
opposite return values... Current -git should work, this is the fix:
