      IB/srp: Fix reconnection failure handling · a44074f1
      Bart Van Assche authored
      Although it is possible to let SRP I/O continue if a reconnect
      results in a reduction of the number of channels, the current
      code does not handle this scenario correctly. Instead of making
      the reconnect code more complex, consider this as a reconnection
      failure.

      IB/srp: Fix connection state tracking · c014c8cd
      Bart Van Assche authored
      Reception of a DREQ message only causes the state of a single
      channel to change. Hence move the 'connected' member variable
      from the target to the channel data structure. This patch
      avoids that following false positive warning can be reported
      by srp_destroy_qp():

      scsi_transport_srp: Introduce srp_wait_for_queuecommand() · be34c62d
      Bart Van Assche authored
      Introduce the helper function srp_wait_for_queuecommand().
      Move the definition of scsi_request_fn_active(). Add a comment
      above srp_wait_for_queuecommand() that support for scsi-mq needs
      to be added.
      
      This patch does not change any functionality. A second call to
      srp_wait_for_queuecommand() will be introduced in the next patch.

      watchdog: Fix merge 'conflict' · ab992dc3
      Peter Zijlstra authored
      Two watchdog changes that came through different trees had a non
      conflicting conflict, that is, one changed the semantics of a variable
      but no actual code conflict happened. So the merge appeared fine, but
      the resulting code did not behave as expected.
      
      Commit 195daf66 ("watchdog: enable the new user interface of the
      watchdog mechanism") changes the semantics of watchdog_user_enabled,
      which thereafter is only used by the functions introduced by
      b3738d29 ("watchdog: Add watchdog enable/disable all functions").
      
      There further appears to be a distinct lack of serialization between
      setting and using watchdog_enabled, so perhaps we should wrap the
      {en,dis}able_all() things in watchdog_proc_mutex.
      
      This patch fixes a s2r failure reported by Michal; which I cannot
      readily explain. But this does make the code internally consistent
      again.

      Pull thermal fixes from Zhang Rui:
       "Specifics:
      
         - fix an issue in intel_powerclamp driver that idle injection target
           is not accurately maintained on newer Intel CPUs.  Package C8 to
           C10 states are introduced on these CPUs but they were not included
           in the package c-state residency calculation.  From Jacob Pan.
      
         - fix a problem that package c-state idle injection was missing on
           Broadwell server, by adding its id to intel_powerclamp driver.
           From Jacob Pan.
      
         - a couple of small fixes and cleanups from Joe Perches, Mathias
           Krause, Dan Carpenter and Anand Moon"
      
      * 'for-rc' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux:
        tools/thermal: tmon: fixed the 'make install' command
        thermal: rockchip: fix an error code
        thermal/powerclamp: fix missing newer package c-states
        thermal/intel_powerclamp: add id for broadwell server
        thermal/intel_powerclamp: add __init / __exit annotations
        thermal: Use bool function return values of true/false not 1/0
