I was debugging some problems with parsing fio jobs, and found
options.c:fio_get_kb_base is broken for external engines... The
parameter
'data' is either 0, td, or td->eo. If it's td->eo it's not really
going to work.
The cleaner fix is probably to unwind passing 'data' so far down the
stack, but it
touches a lot of functions, so I thought I'd send this out now.
unsigned int fio_get_kb_base(void *data)
{
struct thread_options *o = data;
unsigned int kb_base = 0;
if (o)
kb_base = o->kb_base;
if (!kb_base)
kb_base = 1024;
return kb_base;
}
If I replace
if(o)
by
if (o && (data - (void *) threads) % sizeof(threads[0]) == 0)
then it behaves as I expect when engine options use the 'k', etc.
