Subject: [PATCH 04/11] io_uring: don't inflight-track linked timeouts
Git-commit: 761bcac1573efc99042d59add94d468bf17127f0
Patch-mainline: v5.15-rc1
References: bnc#1205205

Tracking linked timeouts as infligh was needed to make sure that io-wq
is not destroyed by io_uring_cancel_generic() racing with
io_async_cancel_one() accessing it. Now, cancellations issued by linked
timeouts are done in the task context, so it's already synchronised.
