From c993df5a688975bf9ce899706ca13d2bc8d6be25 Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Tue, 17 Nov 2020 07:59:16 -0700 Subject: [PATCH] io_uring: don't double complete failed reissue request Zorro reports that an xfstest test case is failing, and it turns out that for the reissue path we can potentially issue a double completion on the request for the failure path. There's an issue around the retry as well, but for now, at least just make sure that we handle the error path correctly.
