Hello,

I'd happily perform some testing, only if the aac(4) driver would also be patched. I know I can run gjournal w/o the BIO_FLUSH feature, but that would make any performance results rather worthles, wouldn't it?

From my tests BIO_FLUSH doesn't have huge impact on performance (if at all), but I suspect it greatly depends on specific HW.

Unfortunately I'm not able to implement BIO_FLUSH to all out storage drivers. Currently BIO_FLUSH is supported by ata(4) (/dev/a[dr]X), da(4) and amr(4).

I see. Does that mean that all CAM-interfaced devices (like asr(4) or twa(4)) have this feature fully implemented?

That's the theory. I'm using standard SCSI commands for this. From the tests we made it seems that it works ok with twa(4)/twe(4). I'd still be glad if someone with SCSI/CAM foo could look at the code.

By the way, this is true for at least the QLogic Fiber channel cards (isp).
