Subject: radix tree test suite: fix allocation calculation in kmem_cache_alloc_bulk()
Date: Fri, 29 Sep 2023 16:13:59 -0400
The bulk allocation is iterating through an array and storing enough
memory for the entire bulk allocation instead of a single array entry.
Only allocate an array element of the size set in the kmem_cache.
