[merged] mm-mark-all-calls-into-the-vmalloc-subsystem-as-potentially-sleeping.patch removed from -mm tree

[akpm]

The patch titled
     Subject: mm: mark all calls into the vmalloc subsystem as potentially sleeping
has been removed from the -mm tree.  Its filename was
     mm-mark-all-calls-into-the-vmalloc-subsystem-as-potentially-sleeping.patch

This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------
From: Christoph Hellwig <hch@lst.de>
Subject: mm: mark all calls into the vmalloc subsystem as potentially sleeping

We will take a sleeping lock in later in this series, so this adds the
proper safeguards.
