The patch titled
Subject: memcg: replace in_interrupt() with !in_task()
has been removed from the -mm tree. Its filename was
memcg-replace-in_interrupt-with-in_task.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Shakeel Butt <shakeelb@xxxxxxxxxx>
Subject: memcg: replace in_interrupt() with !in_task()
Replace the deprecated in_interrupt() with !in_task() because
in_interrupt() returns true for BH disabled even if the call happens in
the task context. in_task() is the right interface to differentiate task
context from NMI, hard IRQ and softirq contexts.
