[RFC 0/1] Is register file feature hard to use ?

[Xiaoguang Wang <xiaoguang.wang@linux.alibaba.com>]

While trying to use register file feature, I think it's hard to use, see
patch-1's commit message for more info.

In this RFC patch, I just propose an preliminary implementation, don't
consider tag, compatibility issue yet, sorry. If we come to a agreement
that it's the right direction, I'll refine it as soon as possible.

Also I saw Pavel has written "io_uring: openat directly into fixed fd table",
which requires user to pass a file_slot. I think it's inconvenient to
user app. We may still reply __get_unused_fd_flags() to allocate a fd,
use it to as slot info.
