commit 825aea662b492571877b32aeeae13689fd9fbee4 upstream.
kernel test robot reports that a recent change of the sqe->rw_flags field throws a sparse warning on 32-bit archs:
io_uring/rw.c:291:19: sparse: sparse: incorrect type in assignment (different base types) @@ expected restricted __kernel_rwf_t [usertype] flags @@ got unsigned int @@
io_uring/rw.c:291:19: sparse: expected restricted __kernel_rwf_t [usertype] flags io_uring/rw.c:291:19: sparse: got unsigned int
Force cast it to rwf_t to silence that new sparse warning.
