[PATCH v2 2/4] Add fp argument to print functions
From: yuzhoujian
Date: Tue Sep 26 2017 - 02:50:17 EST
This patch will add the fp argument to all the print functions so that they can use different
file pointer to print on the screen or dump in the file.
Changes since v1:
- add the __maybe_unused attribute for the fp argument in all the print functions,
because the fp is not used in this patch but needed in the later patches.
- split the original patch(Makes all those related functions receive the FILE
pointer) to two simple patches, and this is the first part.
