Hi Bart,
I took the series as is. But, I don't know the target core well enough
to know what the third patch actually does (that doesn't impact my
decision to take it, it's a knob into the target core to allow you to
tweak things, that's obvious enough and since you find it useful, I have
no problem with it). I know the cmd_per_lun setting sets the queue
depth of the scsi device on the initiator side, I would have assumed
that normally mirrors the advertised ability of the target, but this
patch now makes me think otherwise. So what does this third patch
actually do to the target code?
