[okl4-developer] Memory allocation

[Peter Nguyen]

Hi,

I'm wanting to generate data that is shared between the kernel and user
space. In this particular situation, the purpose here is to generate
sampling data whilst in the kernel that is then read by user threads to
process this sampling data.  More specifically, i want to be able to
generate data and store this in a linked list whilst in the kernel (ie.
i want the kernel to generate this data as well as the linked list
itself).  At the same time, i would like this data to be readable in
user space (ie. to process this data).  I'm wondering whether i am able
to allocate memory in the kernel for this and if so, how?
