__up and __down not found in 2.25 kernel

__up and __down not found in 2.25 kernel

[xavier prabhu]

Hi,

I'm using a module which is developed for 2.22 kernel.
This module uses __up and __down semaphore functions. 
While I insmod this module with 2.25 kernel,
I get the following error message
"insmod: unresolved symbol __up
insmod: unresolved symbol __down"

I checked the semaphore.c. It doesn't define these two functions.
Is there any way to work around this issue.

Please help me to solve this issue.
Thanks in advance.

Regards,
Xavier.

Sounds like you're using some broken tree - get the sources from cvs.

Hi Ralf,

I'm sorry that the version numbers are :
2.4.22 and 2.4.25.

Thanks,
Xavier.

Seems I wasn't yet awake in my previous posting ...

__up and __down are internal semaphore functions.  Do not use them at all;
any such use is not portable.  Looks like you're using a broken module
from i386 or so.
