From 0e48f51cbbfbdb79149806de14dcb8bf0f01ca94 Mon Sep 17 00:00:00 2001 From: Mika Westerberg Date: Fri, 4 Oct 2019 13:00:25 +0300 Subject: Revert "libata, freezer: avoid block device removal while system is frozen" This reverts commit 85fbd722ad0f5d64d1ad15888cd1eb2188bfb557. The commit was added as a quick band-aid for a hang that happened when a block device was removed during system suspend. Now that bdi_wq is not freezable anymore the hang should not be possible and we can get rid of this hack by reverting it. Acked-by: Rafael J.
