Large shared memory segment in kernel

[Stephane Letz <letz@grame.fr>]

We would like to allocate a large memory segment (several Mb) in a kernel
module so that to access the memory in the kernel module and in user space
application. (be implementing the mmap function in the kernel module)
Is is something that could be done ?  Or kernel modules should only mmap
small amount of memory?

Thanks

Stephane Letz
