      vfs: split up name hashing in link_path_walk() into helper function · 200e9ef7
      Linus Torvalds authored
      The code in link_path_walk() that finds out the length and the hash of
      the next path component is some of the hottest code in the kernel.  And
      I have a version of it that does things at the full width of the CPU
      wordsize at a time, but that means that we *really* want to split it up
      into a separate helper function.
      
      So this re-organizes the code a bit and splits the hashing part into a
      helper function called "hash_name()".  It returns the length of the
      pathname component, while at the same time computing and writing the
      hash to the appropriate location.
      
      The code generation is slightly changed by this patch, but generally for
      the better - and the added abstraction actually makes the code easier to
      read too.  And the new interface is well suited for replacing just the
      "hash_name()" function with alternative implementations.

      vfs: clarify and clean up dentry_cmp() · 5707c87f
      Linus Torvalds authored
      It did some odd things for unclear reasons.  As this is one of the
      functions that gets changed when doing word-at-a-time compares, this is
      yet another of the "don't change any semantics, but clean things up so
      that subsequent patches don't get obscured by the cleanups".

      vfs: uninline full_name_hash() · 0145acc2
      Linus Torvalds authored
      .. and also use it in lookup_one_len() rather than open-coding it.
      
      There aren't any performance-critical users, so inlining it is silly.
      But it wouldn't matter if it wasn't for the fact that the word-at-a-time
      dentry name patches want to conditionally replace the function, and
      uninlining it sets the stage for that.
      
      So again, this is a preparatory patch that doesn't change any semantics,
      and only prepares for a much cleaner and testable word-at-a-time dentry
      name accessor patch.

      These don't change any semantics, but they clean up the code a bit and
      mark some arguments appropriately 'const'.
      
      They came up as I was doing the word-at-a-time dcache name accessor
      code, and cleaning this up now allows me to send out a smaller relevant
      interesting patch for the experimental stuff.

      hwmon: (f75375s) Catch some attempts to write to r/o registers · 15d1ad0c
      Nikolaus Schulz authored
      It makes no sense to attempt to manually configure the fan in auto mode,
      or set the duty cycle directly in closed loop mode.  The corresponding
      registers are then read-only.  If the user tries it nonetheless, error out
      with EINVAL instead of silently doing nothing.

      hwmon: (f75375s) Properly map the F75387 automatic modes to pwm_enable · b17d6561
      Nikolaus Schulz authored
      The F75387 supports automatic fan control using either PWM duty cycle or
      RPM speed values.  Make the driver detect the latter mode, and expose the
      different modes in sysfs as per pwm_enable, so that the user can switch
      between them.
      
      The interpretation of the pwm_enable attribute for the F75387 is adjusted
      to be a superset of those values used for similar Fintek chips which do
      not support automatic duty mode, with 2 mapping to automatic speed mode,
      and moving automatic duty mode to the new value 4.
      
      Toggling the duty mode via pwm_enable is currently denied for the F75387,
      as the chip then simply reinterprets the fan configuration register values
      according to the new mode, switching between RPM and PWM units, which
      makes this a dangerous operation.
      
      This patch introduces a new pwm mode into the driver. This is necessary
      because the new mode (automatic pwm mode, 4) may already be enabled by the
      BIOS, and the driver should not break existing functionality. This was seen
      on at least one board.
