Subject: dynamically allocating memory in the kernel

Hello,

I was wondering if someone here could help me understand something about
the kernel for a project I am working on tracking dynamically allocated
memory. How many ways are there to dynamically allocate memory in the
kernel presently? I know of 4.

get_free_pages family of functions
kmalloc family (including vmalloc)
slab allocation
mempools.

Are there others? I am trying to track them all down so I have
comprehensively know when all allocations occur and all "frees".

Thanks for your help,

Carter.
