[PATCH RT 07/13] Revert "fs: jbd2: pull your plug when waiting for space"

From: Steven Rostedt
Date: Wed Jan 17 2018 - 10:18:19 EST


3.18.91-rt98-rc1 stable review patch.
If anyone has any objections, please let me know.

------------------

From: Sebastian Andrzej Siewior <bigeasy@xxxxxxxxxxxxx>

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".
