Pavel Begunkov 36773a78b0 io_uring/msg_ring: let target know allocated index ... commit 5da28edd7bd5518f97175ecea77615bb729a7a28 upstream. msg_ring requests transferring files support auto index selection via IORING_FILE_INDEX_ALLOC, however they don't return the selected index to the target ring and there is no other good way for the userspace to know where is the receieved file. Return the index for allocated slots and 0 otherwise, which is consistent with other fixed file installing requests.
