dm vdo: update vdo_allocate_extended to take a field name, no types

2026-03-02T16:03:18+00:00

All of VDO's "extended" allocations use a flexible array field at the end of the allocated structure. We can infer the struct type from the supplied pointer. Replacing the array field type with the field name lets us use struct_size from overflow.h to compute the size instead of the local __vdo_do_allocation version. One allocation of bio structures doesn't conform to this pattern, since the removal of bi_inline_vecs; directly compute the total size for that case.
