[PATCH 0658/1285] Replace numeric parameter like 0444 with macro

[PATCH 0658/1285] 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.

For what my opinion is worth it... I found more comprehensive the
octal values than the macros, but maybe it is because I am old and
dream in hexadecimal....

I do not know if there is a consensus about this, but if there is not
maybe we should have that discussion before sending a 1K patchset.
