xentrace: Move the global variable t_info_first_offset into calculate_tbuf_size()
|
|
|
|
(xen-unstable changeset 23308:fb5313e64335)
|
|
|
|
Move the global variable t_info_first_offset into
|
|
calculate_tbuf_size() because it is only used there. Change the type
|
|
from u32 to uint32_t to match type in other places.
