Drop the __init on kmemleak_test_init(). With it, the storage is
reclaimed, but then the symbol isn't available for "%pS" rendering,
and the backtrace gets a bare pointer where the actual leak happened.
unreferenced object 0xffff88800a2b0800 (size 1024):
comm "modprobe", pid 413, jiffies 4294953430
hex dump (first 32 bytes):

with __init gone, that trace entry renders like:
