2005-07-14[SCSI] Redundant this_count check in sd_init_command()Chen, Kenneth W
I was going over the scsi I/O submit path, when sd_init_command construct the scsi command, this_count is already checked in the previous else if clause. Why does it need to check it again in the last else block? Patch to delete the spurious check.

2005-07-14[SCSI] Redundant memset in scsi_alloc_sgtableChen, Kenneth W
scsi_init_io calls scsi_alloc_sgtable and then calls blk_rq_map_sg to initialize the scatterlist structure. blk_rq_map_sg() already memset the structure for every new segment. That makes the memset in scsi_alloc_sgtable unnecessary. Patch to delete the extra memset in scsi_alloc_sgtable. Tested on a x86_64 machine. Looks stable to me.

2005-07-14[SCSI] add int_to_scsilun() functionJames.Smart@Emulex.Com
One of the issues we had was reverting the midlayers lun value into the 8byte lun value that we wanted to send to the device. Historically, there's been some combination of byte swapping, setting high/low, etc. There's also been no common thread between how our driver did it and others. I also got very confused as to why byteswap routines were being used. Anyway, this patch is a LLDD-callable function that reverts the midlayer's lun value, stored in an int, to the 8-byte quantity (note: this is not the real 8byte quantity, just the same amount that scsilun_to_int() was able to convert and store originally). This also solves the dilemma of the thread: http://marc.theaimsgroup.com/?l=linux-kernel&m=112116767118981&w=2 A patch for the lpfc driver to use this function will be along in a few days (batched with other patches).

2005-07-14[SCSI] qla2xxx: Cleanup FC remote port registration.Andrew Vasquez
Cleanup FC remote port registration. Due to the inherent behaviour (an immediate scan) of adding a 'target'-role-capable rport via fc_remote_port_add(), split the registration into two steps -- addition as unknown-type role, then use fc_remote_port_rolchg() with appropriate role (based on PLOGI/PRLI bits). This allows for a more cleaner rport->dd_data management as can be seen with the simplified qla2xxx_slave_alloc() function.

2005-07-02[SCSI] lpfc: Fixes in mbox_timeout_handlerJames.Smart@Emulex.Com
Analysis: Timeout of READ_SPARM64 causes call to lpfc_mbox_timeout_handler which reads psli->mbox_active to determine the timeout mbox. Timeout handler then NULL's psli->mbox_active and calls lpfc_mbx_cmpl_read_sparam(), which on timeout condition, calls link_down(). link_down() now calls disc_done() which calls mbox_timeout_hander() again since WORKER_MBOX_TMO is still set, which goes back to read psli->mbox_active which is already NULL'ed. Remove redundant if statement in lpfc_mbox_timeout_handler. pmbox is assigned psli->mbox_active so there is no need to check if it actually equals psli->mbox_active.
