I've updated the source code of kernel 2.4.xxx -- actually I updated the file param.h to enhance the resolution of the timer by changing the HZ (from 100 to 1000) to make the resolution of 1ms granualarity of 1 ms.
I searched the web and found that I must apply a patch if I did this. Here is the info:
about this patch. I don't know if this patch has been applied to my kernel or not (Red Hat Enterprise AS 3.0). If not, I've to apply it.
If you know how to check if a patch has been applied to the kernel or not, please help. Any suggestion would be appreciated.
And then, in the case I've to apply the patch, how can I do it?
