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 Signed-off-by: Glauber Costa <glommer@redhat.com> Signed-off-by: Nick Piggin <npiggin@suse.de> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
