[Xenomai] Problems with xnintr_enable xnintr_disable

[Xenomai] Problems with xnintr_enable xnintr_disable

[Ross Williamson]

I'm in the unfortunate position of having a closed-source kernel
module that I need to recompile a kernel for - I have matched the
kernel version/xenomai version however when I insert the module I get
the folllowing error:

Unknown symbol xnintr_enable
Unknown symbol xnintr_disable

both these symbols are in the System.map for the kernel so I'm
confused as to why the kernel module is reporting this.

Module.symvers:0x00000000 xnintr_enable vmlinux EXPORT_SYMBOL_GPL
System.map:80068270 T xnintr_enable

I suspect I'm doing something dumb....

xnintr_enable and xnintr_disable, like all services exported by Xenomai
in kernel-space, are only available to modules using the GPL license.

Ahhhh.........Well that would explain it.....

I don't think the kernel module I'm using will suddenly become GPL......
