From 4c085cf20f5c0d083aca18680c4323a1fb2b7a1f Mon Sep 17 00:00:00 2001 From: Vincent Fu Date: Thu, 24 Jan 2019 14:26:42 -0500 Subject: [PATCH] rate-submit: call ioengine post_init when starting workers ioengines with post_init steps were not fully fully initialized by offload worker threads because the post_init function was never called. Without this patch all libaio operations submitted in offload mode fail because the ioengine was not fully initialized.
