Hey guys,

I have a really terrible hack, but it appears to work, so...

Dropbox calls statfs64 to get the filesystem type. Now, if only there was a way to change its return value to "ext4"... oh wait, there is!

Here's code of the new function: dropbox_ext4.c

/*

	<?php

	function testPerformance($name, Closure $closure, $runs)
	{
	$start = microtime(true);
	for (; $runs > 0; $runs--)
	{
	$_ = $closure();
	}
	$end = microtime(true);

	/*
	* dropbox_ext4.c
	*
	* Compile like this:
	* gcc -shared -fPIC -ldl -o libdropbox_ext4.so dropbox_ext4.c
	*
	* Run Dropbox like this:
	* LD_PRELOAD=./libdropbox_ext4.so ~/.dropbox-dist/dropboxd
	*/

	<?php
	if (!function_exists('stats_rand_gen_normal')) {
	function stats_rand_gen_normal($mu, $sigma) {
	do {
	$u = (rand() / getrandmax()) * 2 - 1;
	$v = (rand() / getrandmax()) * 2 - 1;
	$s = $u * $u + $v * $v;
	} while ($s >= 1 \|\| $s == 0);

	$multiplier = sqrt(-2 * log($s) / $s);
