Booleans should not be compared to true or false
but be directly tested or tested with !.

Done via cocci script:

bool t;

The ixgbe changes look fine, and I do not see any issues with the
changes.

These are pretty trivial scripts.

You're welcome to add it or combine it
with the one Rusty did to convert
bool foo = 1
to
bool foo = true

It would indeed seem nice to put them all together.  I can do that.

This sort of thing is why I personally don't like 'bool' at all.
If 'is_Pf' were an integer type that is known to only contain 0 or 1
then the code can just be:
	u32 func_encode = func | is_Pf << IGU_FID_ENCODE_IS_PF_SHIFT;
although that is still valid when is_Pf is bool, the compiler
is required to generate code on every access that converts
all non-zero values to 1 - so the generated code is likely
to be 'is_Pf ? 1 : 0'.

The generated code is particularly horrid for boolean arithmetic.
IIRC:
   bool_var &= bool_var_1;
typically requires a sequence of compare and branch instructions.

Properly chosing the bool type is not what is being handled by the
patch. Easiest way to convert would be using double inversion:

u32 func_encode = func | (!!is_Pf << IGU_FID_ENCODE_IS_PF_SHIFT);

The parenthesis are not needed due to operator precedence, but is more
clear this way (to me at least).

I suggest you try to upgrade your old compiler and/or always check your
assertions before posting on netdev such claims.

	bool_var &= bool_var_1;

generates a single AND instruction, no compare, no branch.
It would be a failure from compiler optimizer if that was the case.

And (bool_var ? 1 : 0) or (!!bool_var) are NOP for a compiler as well.

(Only one movzbl instruction to convert a byte to a word if context
requires this)

Only difference for bool or unsigned int vars is type promotion, and
fact that compiler knows that 'bool' only can be 0 or 1, so allows more
optimisations than plain "unsigned int".

Really, bools are not evil if well used.
