No, not the vscsi driver. But the tgt hooks. But yeah, I know. As said, I'll be in touch with them. I just wanted mention that _someone_ uses this code Cheers, Hannes -- Dr. Hannes Reinecke zSeries Storage h...@suse.de +49 911 74053 688 SUSE LINUX Products GmbH, Maxfeldstr. 5, 90409 Nürnberg GF: J.

status of drivers/scsi/scsi_tgt_lib.c
Hi Tomo-san, what is the status of scsi_tgt_lib.c? I've recently been auditing the command allocation and I/O path for various possible improvements, and the use of many functions in this path in addition to the normal initiator code path is going to make a few things a bit harder. The code seems to not have seen any major changes since about 2008, and at least SRP hast another maintained target in mainline. Do you know if either SRP or ibmvscsi are used regularly these days? Does tgtd userspace still support this interface? -- To unsubscribe from this list: send the line unsubscribe linux-scsi in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
