Recent commits to kernel/git/torvalds/linux.git have made the following functions able to tolerate NULL arguments:
kmem_cache_destroy (commit 3942d29918522) mempool_destroy (commit 4e3ca3e033d1) dma_pool_destroy (commit 44d7175da6ea)
These patches remove the associated NULL tests for the files that I found easy to compile test. If these changes are OK, I will address the remainder later.
