I found original some of test function has the prefix `top_down` and

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.

So you're saying use run_top_down() and run_bottom_up() even for functions
with `top_down` and `bottom_up` in the name, but don't change the names?


Yes. We can't delete these `top_down` and `bottom_up` in the name and makes
two functions to have the same name. Due to these functions with `top_down`
and `bottom_up` have different implementation.

If use run_top_down() and run_bottom_up() for these functions. We can get
the consistent output style, but a little redundant output(Maybe this isn't
a good idea).

Yes, I think the output would be too redundant. Even though there are
two different output styles, the style is consistent within each pair of
tests. So there is at least a consistent pattern.


Ok. Just keep the current implementation is fine.

Generic tests for memblock_alloc*() functions do not use separate
functions for testing top-down and bottom-up allocation directions.
Therefore, the function name that is displayed in the verbose testing
output does not include the allocation direction.

Add an additional prefix when running generic tests for
memblock_alloc*() functions that indicates which allocation direction is
set. The prefix will be displayed when the tests are run in verbose mode.
