I suppose that only panasas guys have tested the bidi tree with their OSD target devices. To test the bidi tree, I added XDWRITEREAD_10 support to scsi_debug and sgv4_xdwriteread tool to my makeshift bsg tool collections: git://git.kernel.org/pub/scm/linux/kernel/git/tomo/sgv4-tools.git It just sends XDWRITEREAD_10 commands like this: tulip:~# sgv4_xdwriteread --length 16384 /sys/class/bsg/1:0:0:0 driver:0, transport:0, device:0, din_resid: 0, dout_resid: 0 No errors. I'll send the patchset (over the bidi tree) to add XDWRITEREAD_10 support to scsi_debug though I'm not sure whether it's worth adding it to mainline. - To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
