From: Sebastian Andrzej Siewior Date: Thu, 23 Nov 2017 17:51:51 +0100 Subject: [PATCH] Revert "fs: jbd2: pull your plug when waiting for space" Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.14/older/patches-4.14.1-rt3.tar.xz This reverts commit "fs: jbd2: pull your plug when waiting for space". This was a duct-tape fix which shouldn't be needed since commit "locking/rt-mutex: fix deadlock in device mapper / block-IO".
