So would I, but we've (RTS) been too busy having to work on other stuff
to pay the extensive legal bills from the fallout that your previous
public accusations have wrought.

Even though your over it, it doesn't mean other opportunists did not try
to take advantage of the situation once you got tired and moved onto
other target userspace related things.

In any event, I don't really have a problem with merging the two if your
finally over the fact the userspace code is AGPL licensed.

But please do this in a separate thread than piling on here. Of course,
your more than welcome to fix rtslib for pSCSI, which is broken on
recent v3.x kernels.

(Hint: it's because /sys/class/scsi_device/H:C:T:L/device/block/$BLOCK_DEV
no longer exists in upstream sysfs, which is what we use to match the passed
/dev/$SCSI_DEV to H:C:T:L, and nothing related to TCM ABI changes)
