Proliferation of hundreds of tiny files

[Denys Vlasenko]

Hello Dmitry,

Two years ago, at the end of 2013, strace source had 29 *.c files
in its main source directory (meaning: this does not count any tests).
linux/* contained 148 files in total (not only *.c files).

Today, there are 120 *.c files in main source directory,
and 419 files in linux/*


I have hard time understanding code now. Register reading logic
for x86 is now in what, a dozen different files?

Take a look at x86_64/get_scno.c - what's there is not even a
complete function definition, it's a fragment of C code to be
#included somewhere else. It's hard to see what's being done
where, let alone spot possible bugs or inefficiencies.


Another example:

    file.c: move chdir parser to a separate file


I have a question: Why it's better to have it in a separate file?
I mean, the

#include "defs.h"

SYS_FUNC(chdir)
{
        printpath(tcp, tcp->u_arg[0]);

        return RVAL_DECODED;
}

needs a separate file why?
