Though I don't like neither of the patches, I'll apply one of them so it works
and we can think of a better fix later.

I think first thing is to fix test_add_free_space_entry() :
- replace the map = kzalloc(...) by map = (void *)get_zeroed_page(...) like in
other places.
- replace the kfree(map);

Problem 1: test_add_free_space_entry() contains a kzalloc() to allocate a
bitmap. That's the problem.
Problem 2: btrfs_free_dummy_fs_info() has 3 kfree(). Need to know which

Can you post the changes you did ?
Did you replace the two kzalloc() by get_zeroed_page() as suggested ?
If so, it looks like you missed one kfree() (in free_bitmap()) to be

You can use get_zeroed_page(GFP_NOFS) instead of __get_free_page(GFP_NOFS |

It confirms what I suspected: due to some debug options, kzalloc() doesn't
provide aligned areas.
In __load_free_space_cache() can you replace
e->bitmap = kzalloc(PAGE_SIZE,

In my case it happened on 5.3-rc3, with a strestest. The same machine has been
running fstests periodically, with slab debug on, but there are no slab reports
like that.
