From a1ce35fa49852db60fc6e268038530be533c5b15 Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Mon, 29 Oct 2018 10:23:51 -0600 Subject: block: remove dead elevator code This removes a bunch of core and elevator related code. On the core front, we remove anything related to queue running, draining, initialization, plugging, and congestions. We also kill anything related to request allocation, merging, retrieval, and completion. Remove any checking for single queue IO schedulers, as they no longer exist. This means we can also delete a bunch of code related to request issue, adding, completion, etc - and all the SQ related ops and helpers. Also kill the load_default_modules(), as all that did was provide for a way to load the default single queue elevator.
