[PATCH 5.14 303/334] io_uring: fail links of cancelled timeouts

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Pavel Begunkov <asml.silence@xxxxxxxxx>

commit 2ae2eb9dde18979b40629dd413b9adbd6c894cdf upstream.

When we cancel a timeout we should mark it with REQ_F_FAIL, so
linked requests are cancelled as well, but not queued for further
execution.
