Hi,
Is it possible to share a /proc file between two
kernel modules?
Also, what is the best way to share a structure
between two kernel modules ?
Regards,
-Niranjan

If the two modules are so interrelated, why have them separate?
You can use EXPORT_SYMBOL() to share globals between modules.
I can't see a good reason to ever share a single /proc file.
The module that defines the symbol must be the one that manages
the /proc interaction with that structure.
