Here is a fun patch in an early state. Essentially I want to trace scsi commands, which has already been done long ago. The problem I have is that I care about all the scsi commands for one particular device - without knowing in advance which device it will be. Once I know the device in question, I want to dump the last X commands. The existing tracing is covering all commands to all devices. So either I have to oversize my trace buffer and dump way too much, or I will miss the stuff I am interested in most of the time. Hence my per-device trace buffer (called fdr to avoid namespace collisions).
Isn't this facility something that overlaps with what Wireshark can already do today ? Wireshark can already capture SCSI traces for several transport types (iSCSI, USB, ...). For other transports, e.g. FC, I'd prefer to see Wireshark being extended instead of adding more SCSI tracing mechanisms in the SCSI core.
