[Xenomai-core] rt_heap_bind error -2

[Xenomai-core] rt_heap_bind error -2

[郭宇铮]

Hi, I'm using xenomai instead of fusion.
When I bind a heap in user space which is created by a kernel module, 
the return value is -2 which I don't know what it means for it is not 
one of several values explained by the document.
This program runned well with fusion 0.9.
My kernel is 2.6.13 patched with ipipe.
Can anybody shed light on it?

And there's another strange error. In an ISR, printk must be called or 
the interrupt can't be cleared. So now I add an empty printk to every 
ISR.

Thanks.

Does /dev/rtheap still exist? Maybe something during your update has
killed it.

What do you mean by "cleared"? May a snippet of the ISR would help here
to explain what you do.
