basically would want to know 4294967295 and 2147549184
Something you can try to do is determine the sizeof a dir entry on your system...it's a simple C program to write and it'd give you how much storage each dir entry takes up...although the "no. of entries X sizeof each dir entry" may still not equal the 2147549184 figure...at least that'd be the rationale behind it yet the kernel has complete control over the inner workings of a dir so one cannot be sure of what it's actually doing.

SYNOPSIS
#include <libexplain/readdir.h>
struct dirent *explain_readdir_or_die(DIR *dir);
DESCRIPTION
The explain_readdir_or_die function is used to call the readdir(2) system call. On failure an explanation will be printed to stderr,
obtained from explain_readdir(3), and then the process terminates by calling exit(EXIT_FAILURE).
This function is intended to be used in a fashion similar to the following example:
explain_readdir_or_die(dir);
dir The dir, exactly as to be passed to the readdir(2) system call.
Returns:
a pointer to a dirent structure, or NULL if end-of-file is reached. On failure, prints an explanation and exits.
SEE ALSO
