From 8e608922dfe78786d1a23b86b20da10d8b5455bf Mon Sep 17 00:00:00 2001 From: Mike Snitzer Date: Mon, 28 Dec 2020 16:13:52 -0500 Subject: [PATCH] Revert "dm crypt: export sysfs of kcryptd workqueue" This reverts commit 9934b6c90f8fe28d56c1b8698f7e5664cc6c4e37. WQ_SYSFS breaks the ability to reload a DM table due to sysfs kobject collision (due to active and inactive table). Given lack of demonstrated need for exposing this workqueue via sysfs: revert exposing it.
