[PATCH -mm 3/5] Freezer: Prevent new tasks from inheriting TIF_FREEZE set

[Rafael J. Wysocki]

From: Rafael J. Wysocki <rjw@xxxxxxx>

Tasks should go to the refrigerator only if explicitly requested to do that by
the freezer and not as a result of inheriting the TIF_FREEZE flag set from the
parent.  Make it happen.
