kmemleak does one slab allocation per user allocation. So if slab fault injection is enabled to any degree, kmemleak instantly fails to allocate and turns itself off. However, it's useful to use kmemleak with fault injection to find leaks on error paths. On the other hand, checking kmemleak itself is not so useful because (1) it's a debugging tool and (2) it has a very regular allocation pattern (basically a single allocation site, so it either works or not). Turn off fault injection for kmemleak allocations.
