    Subject[PATCH RT 1/9] Revert "fs: jbd2: pull your plug when waiting for space"
    4.4.102-rt117-rc1 stable review patch.
    If anyone has any objections, please let me know.

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

    From: Sebastian Andrzej Siewior <bigeasy@linutronix.de>

    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".
