      libata, libsas: kill pm_result and related cleanup · bc6e7c4b
      Dan Williams 提交于
      Tejun says:
        "At least for libata, worrying about suspend/resume failures don't make
         whole lot of sense.  If suspend failed, just proceed with suspend.  If
         the device can't be woken up afterwards, that's that.  There isn't
         anything we could have done differently anyway.  The same for resume, if
         spinup fails, the device is dud and the following commands will invoke
         EH actions and will eventually fail.  Again, there really isn't any
         *choice* to make.  Just making sure the errors are handled gracefully
         (ie. don't crash) and the following commands are handled correctly
         should be enough."
      
      The only libata user that actually cares about the result from a suspend
      operation is libsas.  However, it only cares about whether queuing a new
      operation collides with an in-flight one.  All libsas does with the
      error is retry, but we can just let libata wait for the previous
      operation before continuing.
      
      Other cleanups include:
      1/ Unifying all ata port pm operations on an ata_port_pm_ prefix
      2/ Marking all ata port pm helper routines as returning void, only
         ata_port_pm_ entry points need to fake a 0 return value.
      3/ Killing ata_port_{suspend|resume}_common() in favor of calling
         ata_port_request_pm() directly
      4/ Killing the wrappers that just do a to_ata_port() conversion
      5/ Clearly marking the entry points that do async operations with an
        _async suffix.

      libata: end the r-word · 35bf8821
      Dan Williams 提交于
      Prompted by the social effort in the US to discourage usage of the
      adjective "retarded".
      
      In this case we needlessly anthropomorphize hard drives.  The
      implication is that due to design deficiencies in the device reset
      recovery time is negatively impacted.  We can simply clearly state that
      fact.  "Exceptional devices cause outliers in reset recovery time." This
      steers clear of any unintended comparison of such devices to humans with
      cognitive disabilities.
