FD in Kernel 2.4.x

[Federico Edelman Anaya]

Hi! I am newbie in this list! .. I'm Federico Edelman Anaya ... well! ..
I have a question ...

I need increase the FD (File Descriptors) ... I was change the value of
the FD in kernel 2.2.17:

/usr/include/bits/types.h:
#define __FD_SETSIZE    1024    ->  4096

/usr/src/linux/include/linux/posix_types.h
#define __FD_SETSIZE    1024    ->  4096

/usr/src/linux/include/linux/tasks.h
#define NR_TASKS           512     ->  2048   /* On x86 Max 4092, or
4090 w/APM configured. */


Well... Kernel 2.4.3:
/usr/include/bits/types.h:
#define __FD_SETSIZE    1024    ->  4096

/usr/src/linux/include/linux/posix_types.h
#define __FD_SETSIZE    1024    ->  4096

It's only change was posible to do ... Because, tasks.h doesn't exist!

How can I do to increase the FD in the Kernel 2.4.3?

Thanks!
