From 00d23d516e2e7900cd1bd577c1f84794ae7ff3a7 Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Tue, 25 Aug 2020 12:59:22 -0600 Subject: [PATCH] io_uring: ensure read requests go through -ERESTART* transformation We need to call kiocb_done() for any ret < 0 to ensure that we always get the proper -ERESTARTSYS (and friends) transformation done. At some point this should be tied into general error handling, so we can get rid of the various (mostly network) related commands that check and perform this substitution.
