[PATCH 0254/1285] Replace numeric parameter like 0444 with macro

[PATCH 0254/1285] Replace numeric parameter like 0444 with macro

[Baole Ni]

I find that the developers often just specified the numeric value
when calling a macro which is defined with a parameter for access permission.
As we know, these numeric value for access permission have had the corresponding macro,
and that using macro can improve the robustness and readability of the code,
thus, I suggest replacing the numeric parameter with the macro.

I have to ask, why did you ack all these? There's several things wrong with
this patch series, but even the point of the patch is mistaken. It makes
readable code much less readable. When you chmod a file, do you type

  chmod 0444 file

or do you write

  chmod S_IRUSR|S_IRGRP|S_IROTH file

?

Which of the above is easier to figure what is being changed?

Not to mention, because the subject is the same for all 1285 patches, and you
deleted the content of the patch in your ack, there's no way to know what
exactly this ack is for (I haven't received the original patch yet because
it's probably being ratelimited by some mail server).

I assumed this was some global "fix up".

I acked just the single patches that hit cxgb3/cxgb4.  But if this is really
garbage, then ignore my ACKs...

It is, but I'm not so sure I don't agree with Steve.  I'm not sure this
actually makes things better.  At a minimum, I would argue that Bart's
fix is mandatory before they would get my ack.  I would also request
that even though the patches are split up for review, they be squashed
on commit (whoever would want to tackle this monstrous pile of dubious
janitorial stuff).
