for tmp_part->header.name:
it is "Terminating null required only for names < 12 chars".
so need to limit the %.12s for it in printk
additional info:
%12s limit the width, not for the original string output length
if name length is more than 12, it still can be fully displayed.
if name length is less than 12, the ' ' will be filled before name.
%.12s truly limit the original string output length (precision)
