I've been looking at speeding up sym2's queuecommand method. In my current development tree, I've removed most of sym_queue_command() and inlined the remains into sym53c8xx_queuecommand(). There's some funny stuff I wouldn't mind some advice with:
We fail the first command to the device if the device is marked as NOSCAN or the lun is non-0 and the device isn't marked as SCAN LUNS. I think the first part should be moved to slave_alloc(); it's a little weird, but supportable. The second part troubles me a little -- is the blacklist in the midlayer good enough to handle this, or should I leave this mechanism in? The driver currently fails commands sent to the lun of the host adapter. Is this the correct behaviour? What should the driver do? -- "Next the statesmen will invent cheap lies, putting the blame upon the nation that is attacked, and every man will be glad of those conscience-soothing falsities, and will diligently study them, and refuse to examine any refutations of them; and thus he will by and by convince himself that the war is just, and will thank God for the better sleep he enjoys after this process of grotesque self-deception." -- Mark Twain - To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
