| * | | | | [SCSI] libfc: Cleanup return paths in fc_rport_error_retryHillf Danton2011-02-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes it so that we only have one call to fc_rport_error. This patch does not completely consolidate return statements, there is still one return used when not calling fc_rport_error, but alternative solutions made the code more confusing.

| * | | | | [SCSI] libfc: always initialize the FCoE DDP exchange id for fsp as ↵Yi Zou2011-02-12

We should always initialize it as FC_XID_UNKNOWN for a newly allocated fsp, otherwise the fsp allocated in fc_fcp, i.e., not from queuecommand like LUN RESET that is not doing DDP may still think DDP is setup for it since xid 0 is valid and goes on to call fc_fcp_ddp_done() in fc_fcp_resp() from fc_tm_done(). So, set xfer_ddp as FC_XID_UNKNOWN in fc_fcp_pkt_alloc() now. Also removes the setting of fsp->lp as it's already done when fsp is allocated.

| * | | | | [SCSI] Add detailed SCSI I/O errorsHannes Reinecke2011-02-12

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.

| * | | | | [SCSI] pm8001: simplify workqueue usageTejun Heo2011-02-12

It is unnecessarily complex and has a race condition - the works are canceled but not synced, so the work could still be running during and after the data structures are freed. This patch simplifies workqueue usage. * A driver specific workqueue pm8001_wq is created to serve these work items. * To avoid confusion, the "queue" suffixes are dropped from work items and functions. * Delayed queueing was never used. pm8001_work now uses work_struct instead. * The driver no longer keeps track of pending works. All pm8001_works are queued to pm8001_wq and the workqueue is flushed as necessary. flush_scheduled_work() usage is removed during conversion.

The register returns from the PACKET command are all correctly positioned in the device to host register FIS and so we should collect them properly.

'LUN' would still suffice for matching 'LUN C-Mode' but best to explicitly add these new NetApp LUNs to the device list.
