Subject: linux-next: build warning after merge of the block tree

Hi all,

After merging the block tree, today's linux-next build (arm
multi_v7_defconfig) produced this warning:

fs/io_uring.c: In function 'io_accept':
fs/io_uring.c:1729:9: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
 1729 |  addr = (struct sockaddr __user *) READ_ONCE(sqe->addr);
      |         ^
fs/io_uring.c:1730:13: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
 1730 |  addr_len = (int __user *) READ_ONCE(sqe->addr2);
      |             ^

Introduced by commit

  d674c2b9335f ("io_uring: add support for IORING_OP_ACCEPT")

addr and addr2 are __u64 ...

Cheers,
