      blk: rq_data_dir() should not return a boolean · 10fbd36e
      Linus Torvalds authored
      rq_data_dir() returns either READ or WRITE (0 == READ, 1 == WRITE), not
      a boolean value.
      
      Now, admittedly the "!= 0" doesn't really change the value (0 stays as
      zero, 1 stays as one), but it's not only redundant, it confuses gcc, and
      causes gcc to warn about the construct
      
          switch (rq_data_dir(req)) {
              case READ:
                  ...
              case WRITE:
                  ...
      
      that we have in a few drivers.
      
      Now, the gcc warning is silly and stupid (it seems to warn not about the
      switch value having a different type from the case statements, but about
      _any_ boolean switch value), but in this case the code itself is silly
      and stupid too, so let's just change it, and get rid of warnings like
      this:
      
        drivers/block/hd.c: In function ‘hd_request’:
        drivers/block/hd.c:630:11: warning: switch condition has boolean value [-Wswitch-bool]
           switch (rq_data_dir(req)) {
      
      The odd '!= 0' came in when "cmd_flags" got turned into a "u64" in
      commit 5953316d ("block: make rq->cmd_flags be 64-bit") and is
      presumably because the old code (that just did a logical 'and' with 1)
      would then end up making the type of rq_data_dir() be u64 too.
      
      But if we want to retain the old regular integer type, let's just cast
      the result to 'int' rather than use that rather odd '!= 0'.

      Merge branch 'writeback-plugging' · e1df8b0a
      Linus Torvalds authored
      Fix up the writeback plugging introduced in commit d353d758
      ("writeback: plug writeback at a high level") that then caused problems
      due to the unplug happening with a spinlock held.
      
      * writeback-plugging:
        writeback: plug writeback in wb_writeback() and writeback_inodes_wb()
        Revert "writeback: plug writeback at a high level"

      writeback: plug writeback in wb_writeback() and writeback_inodes_wb() · 505a666e
      Linus Torvalds authored
      We had to revert the pluggin in writeback_sb_inodes() because the
      wb->list_lock is held, but we could easily plug at a higher level before
      taking that lock, and unplug after releasing it.  This does that.
      
      Chris will run performance numbers, just to verify that this approach is
      comparable to the alternative (we could just drop and re-take the lock
      around the blk_finish_plug() rather than these two commits.
      
      I'd have preferred waiting for actual performance numbers before picking
      one approach over the other, but I don't want to release rc1 with the
      known "sleeping function called from invalid context" issue, so I'll
      pick this cleanup version for now.  But if the numbers show that we
      really want to plug just at the writeback_sb_inodes() level, and we
      should just play ugly games with the spinlock, we'll switch to that.

      thermal: fix intel PCH thermal driver mismerge · dfb22fc5
      Linus Torvalds authored
      I didn't notice this when merging the thermal code from Zhang, but his
      merge (commit 5a924a07: "Merge branches 'thermal-core' and
      'thermal-intel' of .git into next") of the thermal-core and
      thermal-intel branches was wrong.
      
      In thermal-core, commit 17e8351a ("thermal: consistently use int for
      temperatures") converted the thermal layer to use "int" for
      temperatures.
      
      But in parallel, in the thermal-intel branch commit d0a12625
      ("thermal: Add Intel PCH thermal driver") added support for the intel
      PCH thermal sensor using the old interfaces that used "unsigned long"
      pointers.
      
      This resulted in warnings like this:
      
        drivers/thermal/intel_pch_thermal.c:184:14: warning: initialization from incompatible pointer type [-Wincompatible-pointer-types]
          .get_temp = pch_thermal_get_temp,
                      ^
        drivers/thermal/intel_pch_thermal.c:184:14: note: (near initialization for ‘tzd_ops.get_temp’)
        drivers/thermal/intel_pch_thermal.c:186:19: warning: initialization from incompatible pointer type [-Wincompatible-pointer-types]
          .get_trip_temp = pch_get_trip_temp,
                           ^
        drivers/thermal/intel_pch_thermal.c:186:19: note: (near initialization for ‘tzd_ops.get_trip_temp’)
      
      This fixes it.
