    [SCSI] zfcp: enhancement of zfcp debug features · 8a36e453
    Maxim Shchetynin authored
    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.
