tracing: typecast sizeof and offsetof to unsigned int
Impact: fix compiler warnings On x86_64 sizeof and offsetof are treated as long, where as on x86_32 they are int. This patch typecasts them to unsigned int to avoid one arch giving warnings while the other does not. Reported-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Steven Rostedt <srostedt@redhat.com>
