Now that the VFS stuff appears to stabilize I agree it's a good time to revisit all this. I just merged the required VPD patches from Hannes so those will be in 4.5. I have a bunch of changes to the SCSI code that I worked on over the spring/summer based on a feedback from the array vendors after discussions we started at LSF/MM. Generally speaking, their comments didn't make things easier, nor prettier :( But your two bio approach is a requirement to accommodate those needs (token-based copy) so I'll work on consolidating your changes with mine. That said, we still need Mike Christie's patches to go in first. Mike: What's your status? I'm afraid I didn't get a chance to dig very deep in your series since it coincided with me scrambling to sort out SCSI for 4.4. Do you think there's a chance we could get your patches in shape for 4.5? Is there an up-to-date tree I can look at? -- Martin K.
