According to the FSF spec, word 0 (bytes 0-3) has the handle specified with the abort command and word 1 (bytes 4-7) has the handle for the command to be aborted.

There is a possible race condition while generating the unique request ids and sequence numbers. Both might be read at the same time and have the same value. Fix this by serializing the access through the queue lock of the adapter: First call zfcp_fsf_req_sbal_get that acquires the lock, then read and increment the unique ids.

this patch adds some fc host attributes and removes its equivalents from the zfcp_adapter structure and zfcp specific sysfs subtree. Furthermore it removes superfluous calls to fc_remort_port_delete when an adapter is set offline because rports will be removed by fc_remove_host anyway.

Debug features (DBFs) els_dbf, cmd_dbf and abt_dbf were removed and san_dbf, hba_dbf and scsi_dbf were introduced. The erp_dbf did not change. The new traces improve debugging of problems with zfcp, scsi-stack, multipath and hardware in the SAN. san_dbf traces things like ELS and CT commands, hba_dbf saves HBA specific information of requests, and scsi_dbf saves FCP and SCSI specific information of requests. Common to all new DBFs is that they provide a so called structured view. This significantly improves readability of the traces.

Fixes a race between zfcp_fsf_req_dismiss_all and zfcp_qdio_reqid_check. During adapter shutdown it occurred that a request was cleaned up twice. First during its normal completion. Second when dismiss_all was called. The fix is to serialize access to fsf request list between zfcp_fsf_req_dismiss_all and zfcp_qdio_reqid_check and delete a fsf request from the list if its completion is triggered. (Additionally a rwlock was replaced by a spinlock and fsf_req_cleanup was eliminated.)
