      [S390] path grouping and path verifications fixes. · 7e560814
      Cornelia Huck authored
      
      
      1. Multipath devices for which SetPGID is not supported are not handled well.
         Use NOP ccws for path verification (sans path grouping) when SetPGID is not
         supported.
      2. Check for PGIDs already set with SensePGID on _all_ paths (not just the
         first one) and try to find a common one. Moan if no common PGID can be
         found (and use NOP verification). If no PGIDs have been set, use the css
         global PGID (as before). (Rationale: SetPGID will get a command reject if
         the PGID it tries to set does not match the already set PGID.)
      3. Immediately before reboot, issue RESET CHANNEL PATH (rcp) on all chpids. This
         will remove the old PGIDs. rcp will generate solicited CRWs which can be
         savely ignored by the machine check handler (all other actions create
         unsolicited CRWs).

      [S390] rework of channel measurement facility. · 94bb0633
      Cornelia Huck authored
      
      
      Fixes for several channel measurement facility bugs:
      * Blocks copied from the hardware might not be consistent. Solve this
        by moving the copying into idle state and repeating the copying.
      * avg_sample_interval changed with every read, even though no new block
        was available. Solve this by storing a timestamp when the last new
        block was received.
      * Several locking issues.
      * Measurements were not reenabled after a disconnected device became
        available again.
      * Remove #defines for ioctls that were never implemented.

      [S390] cio chpid offline. · b4f7b1ee
      Cornelia Huck authored
      
      
      After setting a path to a dasd offline at the SE, I/O hangs on that
      dasd for 5 minutes, then continues.
      I/O for which an interrupt will not be reported after the channel
      path has been disabled was not terminated by the common I/O layer,
      causing the dasd MIH to hit after 5 minutes.
      
      Be more aggressive in terminating I/O after setting a channel path
      offline. Also make sure to generate a fake irb if the device
      driver issues an I/O request after being notified of the killed
      I/O and clear residual information from the irb before trying to
      start the delayed verification.
