2009-06-10[SCSI] osduld: use filp_open() when looking up an osd-deviceBoaz Harrosh
This patch was inspired by Al Viro, for simplifying and fixing the retrieval of osd-devices by in-kernel users, eg: file systems. In-Kernel users, now, go through the same path user-mode does by opening a file on the osd char-device and though holding a reference to both the device and the Module. A file pointer was added to the osd_dev structure which is now allocated for each user. The internal osd_dev is no longer exposed outside of the uld. I wanted to do that for a long time so each libosd user can have his own defaults on the device. The API is left the same, so user code need not change. It is no longer needed to open/close a file handle on the osd char-device from user-mode, before mounting an exofs on it.

2009-06-10[SCSI] libosd: Define an osd_dev wrapper to retrieve the request_queueBoaz Harrosh

2009-06-10[SCSI] libosd: osd_req_{read,write} takes a length parameterBoaz Harrosh
For supporting of chained-bios we can not inspect the first bio only, as before. Caller shall pass the total length of the request, ie. sum_bytes(bio-chain). Also since the bio might be a chain we don't set it's direction on behalf of it's callers. The bio direction should be properly set prior to this call. So fix a couple of write users that now need to set the bio direction properly [In this patch I change both library code and user sites at exofs, to make it easy on integration. It should be submitted via James's scsi-misc tree.] Signed-off-by: Boaz Harrosh <bharrosh@panasas.com> CC: Jeff Garzik <jeff@garzik.org> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
2009-06-10[SCSI] libosd: Let _osd_req_finalize_data_integrity receive number of out_bytesBoaz Harrosh
_osd_req_finalize_data_integrity was trying to deduce the number of out_bytes from passed osd_request->out.bio. This is wrong when the bio is chained. The caller of _osd_req_finalize_data_integrity has more ready available information and should just pass it. Also in the light of future support for CDB-continuation segment this is a better solution.

2009-06-08[SCSI] ibmvscsi: Add support for capabilities MADBrian King
Add support to ibmvscsi for the capabilities MAD. This command gets sent to the Virtual I/O server prior to login in order to communicate client capabilities. Additionally it returns information regarding capabilities that the server supports. The two main capabilities communicated in this MAD are related to partition migration and client reserve. Client reserve allows for SCSI-2 reservations to be sent to virtual disks which are backed by physical LUNs and will result in the reservation being sent to the physical LUN.

2009-06-08[SCSI] ibmvscsi: Enable fast fail featureRobert Jennings
A new mode of error reporting, fast fail, has been added to the VIOS which allows failover to happen more quickly. If this new fast fail mode is enabled on the VIOS and the vSCSI client supports the mode, the VIOS will not return MEDIUM error on path failures, but rather return VIOSRP_ADAPTER_FAIL in the crq response, which ibmvscsi will translate to DID_ERROR. This new mode can be enabled for single path configurations as well, so it is the new default error reporting mode. A module parameter is provided to disable this new behavior on the off chance it causes a problem on some old VIOS version.

2009-06-08[SCSI] ibmvscsi: Send adapter info before loginBrian King
The ibmvscsi driver currently sends the SRP Login before sending the Adapter Info MAD, which can result in commands getting sent to the virtual adapter before we are ready for them. This results in a slight window where the target devices may not behave as expected. Change the order and close the window.

2009-06-08[SCSI] qla2xxx: Use 'proper' DID_* status code for dropped-frame scenarios.Andrew Vasquez

2009-06-08[SCSI] fcoe: removes fcoe_watchdogVasu Dev
Removes periodic fcoe_watchdog timer used across all fcoe interface maintained in fcoe_hostlist instead added new fcoe_queue_timer per fcoe interface. Added timer is armed only when some pending skb need to be flushed as oppose to periodic 1 second fcoe_watchdog, since now fcoe_queue_timer is used on demand thus set this to 2 jiffies. Now fcoe_queue_timer is much simple than fcoe_watchdog using lock to process all fcoe interface from fcoe_hostlist. I noticed +ve performance result with using 2 jiffies timer as this helps flushing fcoe_pending_queue quickly.

2009-06-08[SCSI] fcoe: reduces lock cost when adding a new skb to fcoe_pending_queueVasu Dev
Currently fcoe_pending_queue.lock held twice for every new skb adding to this queue when already least one pkt is pending in this queue and that is not uncommon once skb pkts starts getting queued here upon fcoe_start_io => dev_queue_xmit failure. This patch moves most fcoe_pending_queue logic to fcoe_check_wait_queue function, this new logic grabs fcoe_pending_queue.lock only once to add a new skb instead twice as used to be. I think after this patch call flow around fcoe_check_wait_queue calling in fcoe_xmit is bit simplified with modified fcoe_check_wait_queue function taking care of adding and removing pending skb in one function.
