LTP needs fixing.
tst_max_swapfiles() detects the number of supported swapfiles by parsing
the kernel config, expecting that with CONFIG_DEVICE_PRIVATE we'd use 4
on newer kernels.
Now it's "3", and consequently we support one more swapfile which the
test cannot deal with (expecting a failure)
So, all good from a kernel perspective.
