Subject: rate-submit: call ioengine post_init when starting workers
X-Git-Tag: fio-3.13~10
X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=4c085cf20f5c0d083aca18680c4323a1fb2b7a1f;p=fio.git

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.

Fixes: 2041bd343da1 ("engines/libaio: add preliminary support for pre-mapped IO buffers")
