[uml-devel] mmap in a uml device driver

[Greg L. <gl...@ri...>]

Hi,

I am trying to write a uml device driver that uses mmap() to map in a 
file from the host to uml.  I want the host, a uml kernel thread and 
user mode linux user processes to be able to modify the file using 
mmap().  But, I am having troubles with the kernel thread segfaulting in 
uml on a write to the memory location returned by mmap().   Is this 
possible?  Any ideas on how to support this functionality?

Thanks,
Greg
