* [SCSI] bnx2i: set change_queue_depth functionMike Christie2010-02-17
| | | | | | | | | No reason that we cannot set the change_queue_depth function for bnx2i. We just forgot to when the driver was created. Signed-off-by: Mike Christie <michaelc@cs.wisc.edu> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
* [SCSI] libiscsi: reset cmd timer if cmds are making progressMike Christie2010-02-17
| | | | | | | | | | | | | | | | | | | | | | This patch resets the cmd timer if cmds started before the timedout command are making progress. The idea is that the cmd probably timed out because we are trying to exeucte too many commands. If it turns out that the device the IO timedout on was bad or the cmd just got screwed up but other IO/devs were ok then we will will figure this out when the cmds ahead of the timed out one complete ok. This also fixes a bug where we were sort of detecting this by setting the last_timeout and last_xfer to the same value when the task was allocated. That caught the case where we never got to send any IO for it. However, if the problem had started right before we started the new task, then we were forced to wait an extra cmd timeout seconds to start the scsi eh.

* [SCSI] cxgb3i: check for setup netdevMike Christie2010-02-17
| | | | | | | | | | | | | If the netdev has not been setup when the host is, we will oops when the iscsi layer calls into the driver and a it tries to reference the netdev in hba->ndev. This can happen if the iscsi driver is loaded before ifup is done. This patch just adds a check, so we can gracefully fail the operation.

* [SCSI] hpsa: fix bug in adjust_hpsa_scsi_tableStephen M. Cameron2010-02-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | fix bug in adjust_hpsa_scsi_table which caused devices which have changed size, etc. to do the wrong thing. The problem was as follows: The driver maintains its current idea of what devices are present in the h->dev[] array. When it updates this array, it scans the hardware, and produces a new list of devices, call it sd[], for scsi devices. Then, it compares each item in h->dev[] vs. sd[], and any items which are not present sd it removes from h->dev[], and any items present in sd[], but different, it modifies in h->dev[]. Then, it looks for items in sd[] which are not present in h->dev[], and adds those items into h->dev[]. All the while, it keeps track of what items were added and removed to/from h->dev[]. Finally, it updates the SCSI mid-layer by removing and adding the same devices it removed and added to/from h->dev[]. (modified devices count as a remove then add.) originally, when a "changed" device was discovered, it was removed then added to h->dev[]. The item was added to the *end* of h->dev[]. And, the item was removed from sd[] as well (nulled out). As it processed h->dev[], these newly added items at the end of the list were encountered, and sd[] was searched, but those items were nulled out. So they ended up getting removed immediately after they were added. The solution is to have a way to replace items in the h->dev[] array instead of doing a remove + add. Then the "changed" items. are not encountered a second time, and removed. Signed-off-by: Stephen M. Cameron <scameron@beardog.cce.hp.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
