mm: vmalloc improve vmallocinfo
If we do that, output of files like /proc/vmallocinfo will show things
like "vmalloc_32", "vmalloc_user", or whomever the caller was as the
caller. This info is not as useful as the real caller of the allocation.
So, proposal is to call __vmalloc_node node directly, with matching
parameters to save the caller information
