Research direction

Start at the Uffd::into_raw_fd implementation and compare its ownership behavior with Uffd::drop. Verify the conversion returns the file descriptor without closing it, and confirm the descriptor remains usable after the Uffd value is consumed.

Written by the indexing model from the issue text.

Description

The current implementation of the IntoRawFd trait doesn't seem to work correctly. When calling Uffd::into_raw_fd the method correctly returns the fd, but it also ends up calling Uffd::drop which immediately closes the fd.
