Currently functions in zsmalloc.c does not arranged in a readable and
reasonable sequence. With the more and more functions added, we may
meet below inconvenience. For example:
Current functions:
void zs_init()
{
}
static void get_maxobj_per_zspage()
{
}
Then I want to add a func_1() which is called from zs_init(), and this
new added function func_1() will used get_maxobj_per_zspage() which is
defined below zs_init().
void func_1()
{
get_maxobj_per_zspage()
}
void zs_init()
{
func_1()
}
static void get_maxobj_per_zspage()
{
}
This will cause compiling issue. So we must add a declaration:
static void get_maxobj_per_zspage();
before func_1() if we do not put get_maxobj_per_zspage() before
func_1().
In addition, puting module_[init|exit] functions at the bottom of the
file conforms to our habit.
So, this patch ajusts function sequence as:
/* helper functions */
...
obj_location_to_handle()
...
/* Some exported functions */
...
zs_map_object()
zs_unmap_object()
zs_malloc()
zs_free()
zs_init()
zs_exit()
