Subject: Re: [PATCH 3/8] memblock tests: add labels to verbose output for
generic alloc tests
I found original some of test function has the prefix `top_down` and
`bottom_up`, and some of test function didn't have the prefix.
In this patch, it just modified these functions which didn't have the
prefix `top_down` or `bottom_up`, and now there are two style about
these test functions in the code.
One is:
run_top_down(alloc_in_between_generic_check);
run_bottom_up(alloc_in_between_generic_check);
Another one is:
memblock_set_bottom_up(false);
alloc_top_down_before_check();
memblock_set_bottom_up(true);
alloc_bottom_up_before_check();
Thus there gonna be two output style, here is an example:
ok 89 : memblock_alloc_from: top-down: alloc_from_simple_generic_check:
passed
ok 90 : memblock_alloc_from: bottom-up: alloc_from_simple_generic_check:
passed
ok 99 : memblock_alloc_try_nid: alloc_try_nid_top_down_simple_check: passed
ok 100 : memblock_alloc_try_nid: alloc_try_nid_bottom_up_simple_check:
passed
It may make confuse if one is printed between the colon and one is
inside the function name.
So maybe make the style consistent is more make sense. And I think this
can be done by modify all these function name which with `top_down` and
`bottom_up` inside, and replace them with your new run_top_down() and
run_bottom_up() functions.
