ore_components already has a comps member so this leads to things like comps->comps which is annoying. the name oc was already used in new code. So rename all old usage of ore_components comps => ore_components oc. Signed-off-by: NBoaz Harrosh <bharrosh@panasas.com>

ORE stands for "Objects Raid Engine" This patch is a mechanical rename of everything that was in ios.c and its API declaration to an ore.c and an osd_ore.h header. The ore engine will later be used by the pnfs objects layout driver. * File ios.c => ore.c * Declaration of types and API are moved from exofs.h to a new osd_ore.h * All used types are prefixed by ore_ from their exofs_ name. * Shift includes from exofs.h to osd_ore.h so osd_ore.h is independent, include it from exofs.h. Other than a pure rename there are no other changes. Next patch will move the ore into it's own module and will export the API to be used by exofs and later the layout driver Signed-off-by: NBoaz Harrosh <bharrosh@panasas.com>

The fcoe driver can implement ddp_targ() similarly to ddp_setup() when fcoe stack works with existing target frame, e.g., tcm, where the ddp_targ() would eventually point to the underlying hardware driver's implementation of ndo_fcoe_ddp_targ() through net_device_ops.

Commit c21e6beb removed our queue request_fn re-enter protection, and defaulted to always running the queues from kblockd to be safe. This was a known potential slow down, but should be safe. Unfortunately this is causing big performance regressions for some, so we need to improve this logic. Looking into the details of the re-enter, the real issue is on requeue of requests. Requeue of requests upon seeing a BUSY condition from the device ends up re-running the queue, causing traces like this: scsi_request_fn() scsi_dispatch_cmd() scsi_queue_insert() __scsi_queue_insert() scsi_run_queue() scsi_request_fn() ... potentially causing the issue we want to avoid. So special case the requeue re-run of the queue, but improve it to offload the entire run of local queue and starved queue from a single workqueue callback. This is a lot better than potentially kicking off a workqueue run for each device seen. This also fixes the issue of the local device going into recursion, since the above mentioned commit never moved that queue run out of line. Signed-off-by: NJens Axboe <jaxboe@fusionio.com>

During device discovery, scsi mid layer sends INQUIRY command to LUN 0. If the LUN 0 is not mapped to host, it creates a temporary scsi_device with LUN id 0 and sends REPORT_LUNS command to it. After the REPORT_LUNS succeeds, it walks through the LUN table and adds each LUN found to sysfs. At the end of REPORT_LUNS lun table scan, it will delete the temporary scsi_device of LUN 0. When scsi devices are added to sysfs, it calls add_dev function of all the registered class interfaces. If ses driver has been registered, ses_intf_add() of ses module will be called. This function calls scsi_device_enclosure() to check the inquiry data for EncServ bit. Since inquiry was not allocated for temporary LUN 0 scsi_device, it will cause NULL pointer exception. To fix the problem, sdev->inquiry is checked for NULL before reading it.

The conversion is quite complex given that the libata new error handler has to be hooked into the current libsas timeout and error handling. The way this is done is to process all the failed commands via libsas first, but if they have no underlying sas task (and they're on a sata device) assume they are destined for the libata error handler and send them accordingly. Finally, activate the port recovery of the libata error handler for each port known to the host. This is somewhat suboptimal, since that port may not need recovering, but given the current architecture of the libata error handler, it's the only way; and the spurious activation is harmless.

For drivers using the ep callbacks the addr and port are attached to the endpoint instead of the conn. This adds a callout to the iscsi_transport to get ep values. It also adds locking around the get param call to make sure that ep_disconnect does not free the LLD's ep interconnect structs from under us (the ep has a refcount so it will not go away but the LLD may have structs from other subsystems that are not allocated in the ep so we need to protect them from getting freed).

Allow FC-4 provider modules to hook into libfc, mostly for targets. This should allow any FC-4 module to handle PRLI requests and maintain process-association states. Each provider registers its ops with libfc and then will be called for any incoming PRLI for that FC-4 type on any instance. The provider can decide whether to handle that particular instance using any method it likes, such as ACLs or other configuration information. A count is kept of the number of successful PRLIs from the remote port. Providers are called back with an implicit PRLO when the remote port is about to be deleted or has been reset. fc_lport_recv_req() now sends incoming FC-4 requests to FC-4 providers, and there is a built-in provider always registered for handling incoming ELS requests. The call to provider recv() routines uses rcu_read_lock() so that providers aren't removed during the call. That lock is very cheap and shouldn't affect any performance on ELS requests. Providers can rely on the RCU lock to protect a session lookup as well.

Instead of just passing 'EIO' for any I/O error we should be notifying the upper layers with more details about the cause of this error. Update the possible I/O errors to: - ENOLINK: Link failure between host and target - EIO: Retryable I/O error - EREMOTEIO: Non-retryable I/O error - EBADE: I/O error restricted to the I_T_L nexus 'Retryable' in this context means that an I/O error _might_ be restricted to the I_T_L nexus (vulgo: path), so retrying on another nexus / path might succeed. 'Non-retryable' in general refers to a target failure, so this error will always be generated regardless of the I_T_L nexus it was send on. I/O errors restricted to the I_T_L nexus might be retried on another nexus / path, but they should _not_ be queued if no paths are available.
