[PATCH 5.9 72/74] io_uring: dont reuse linked_timeout

[Greg Kroah-Hartman]

From: Pavel Begunkov <asml.silence@xxxxxxxxx>

commit ff5771613cd7b3a76cd16cb54aa81d30d3c11d48 upstream.

Clear linked_timeout for next requests in __io_queue_sqe() so we won't
queue it up unnecessary when it's going to be punted.
