From 3746d62ecf1c872a520c4866118edccb121c44fd Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Thu, 23 Jun 2022 11:06:43 -0600 Subject: [PATCH] io_uring: use original request task for inflight tracking commit 386e4fb6962b9f248a80f8870aea0870ca603e89 upstream. In prior kernels, we did file assignment always at prep time. This meant that req->task == current. But after deferring that assignment and then pushing the inflight tracking back in, we've got the inflight tracking using current when it should in fact now be using req->task. Fixup that error introduced by adding the inflight tracking back after file assignments got modifed.
