From eba6f5a330cf042bb0001f0b5e8cbf21be1b25d6 Mon Sep 17 00:00:00 2001 From: Pavel Begunkov Date: Tue, 28 Jan 2020 03:15:47 +0300 Subject: io-wq: allow grabbing existing io-wq Export a helper to attach to an existing io-wq, rather than setting up a new one. This is doable now that we have reference counted io_wq's.
