    Subject[PATCH 5.7 431/477] io_uring: dont fail links for EAGAIN error in IOPOLL mode
    Date
    From: Xiaoguang Wang <xiaoguang.wang@linux.alibaba.com>

    [ Upstream commit 2d7d67920e5c8e0854df23ca77da2dd5880ce5dd ]

    In IOPOLL mode, for EAGAIN error, we'll try to submit io request
    again using io-wq, so don't fail rest of links if this io request
    has links.
