      blktrace: Provide event for request merging · f3bdc62f
      Jan Kara authored
      Currently blk-mq does not report any event when two requests get merged
      in the elevator. This then results in difficult to understand sequence
      of events like:
      
      ...
        8,0   34     1579     0.608765271  2718  I  WS 215023504 + 40 [dbench]
        8,0   34     1584     0.609184613  2719  A  WS 215023544 + 56 <- (8,4) 2160568
        8,0   34     1585     0.609184850  2719  Q  WS 215023544 + 56 [dbench]
        8,0   34     1586     0.609188524  2719  G  WS 215023544 + 56 [dbench]
        8,0    3      602     0.609684162   773  D  WS 215023504 + 96 [kworker/3:1H]
        8,0   34     1591     0.609843593     0  C  WS 215023504 + 96 [0]
      
      and you can only guess (after quite some headscratching since the above
      excerpt is intermixed with a lot of other IO) that request 215023544+56
      got merged to request 215023504+40. Provide proper event for request
      merging like we used to do in the legacy block layer.

       "Some early fixes collected during the first week after the merge
        window, all pretty self-evident, with the details below. The revert is
        the crucial thing.
      
         - Fix a warning on the Qualcomm SPMI GPIO chip being instatiated
           twice without a unique irqchip struct
      
         - Use the noirq variants of the suspend and resume callbacks in the
           Tegra driver
      
         - Clean up the errorpath on the MCP23s08 driver
      
         - Revert the use of devm_of_iomap() in the Freescale driver as it was
           regressing the platform
      
         - Add some missing pins in the Qualcomm IPQ6018 driver

      Pull powerpc fixes from Michael Ellerman:
      
       - One fix for the interrupt rework we did last release which broke
         KVM-PR
      
       - Three commits fixing some fallout from the READ_ONCE() changes
         interacting badly with our 8xx 16K pages support, which uses a pte_t
         that is a structure of 4 actual PTEs
      
       - A cleanup of the 8xx pte_update() to use the newly added pmd_off()
      
       - A fix for a crash when handling an oops if CONFIG_DEBUG_VIRTUAL is
         enabled
      
       - A minor fix for the SPU syscall generation
