The __opt annotation was originally introduced specifically for
buffer/size argument pairs in bpf_dynptr_slice() and
bpf_dynptr_slice_rdwr(), allowing the buffer pointer to be NULL while
still validating the size as a constant. The __nullable annotation
serves the same purpose but is more general and is already used
throughout the BPF subsystem for raw tracepoints, struct_ops, and other
kfuncs.
This patch unifies the two annotations by replacing __opt with
__nullable. The key change is in the verifier's
get_kfunc_ptr_arg_type() function, where mem/size pair detection is now
performed before the nullable check. This ensures that buffer/size
pairs are correctly classified as KF_ARG_PTR_TO_MEM_SIZE even when the
buffer is nullable, while adding an !arg_mem_size condition to the
nullable check prevents interference with mem/size pair handling.
When processing KF_ARG_PTR_TO_MEM_SIZE arguments, the verifier now uses
is_kfunc_arg_nullable() instead of the removed is_kfunc_arg_optional()
to determine whether to skip size validation for NULL buffers.
This is the first documentation added for the __nullable annotation,
which has been in use since it was introduced but was previously
undocumented.
No functional changes to verifier behavior - nullable buffer/size pairs
continue to work exactly as before.

In unittest_data_add(), if of_resolve_phandles() fails, the allocated
unittest_data is not freed, leading to a memory leak.
Fix this by using scope-based cleanup helper __free(kfree) for automatic
resource cleanup. This ensures unittest_data is automatically freed when
it goes out of scope in error paths.
For the success path, use retain_and_null_ptr() to transfer ownership
of the memory to the device tree and prevent double freeing.
