Nirjhar Roy 811808d365 mm/kfence: add a new kunit test test_use_after_free_read_nofault() ... Faults from copy_from_kernel_nofault() need to be handled by fixup table and should not be handled by kfence. Otherwise while reading /proc/kcore which uses copy_from_kernel_nofault(), kfence can generate false negatives. This can happen when /proc/kcore ends up reading an unmapped address from kfence pool. Let's add a testcase to cover this case.
