Query on freeing of new_fdt->open_fds inside src/fs/file.c

[pavi1729]

Hi,
   I am unable to understand how

   new_fdt->open_fds can be freed in __free_fdtable when its an
unsigned long in files_struct ?


Details:

FUNCTION: dup_fd
http://lxr.free-electrons.com/source/fs/file.c#L261

LINE : 282 : new_fdt->open_fds = newf->open_fds_init;

files_struct : http://lxr.free-electrons.com/source/include/linux/fdtable.h#L45
unsigned long open_fds_init[1];


Cheers,
Pavi
