Hugh Dickins explains:

 "It seems too little tested: "losetup -d /dev/loop0" fails with
  EINVAL because nothing sets lo_thread; but even when you patch
  loop_thread() to set lo->lo_thread = current, it can't survive
  more than a few dozen iterations of the loop below (with a tmpfs
  mounted on /tst):

j=0
cp /dev/zero /tst
while :
do
    let j=j+1
    echo "Doing pass $j"
    losetup /dev/loop0 /tst/zero
    mkfs -t ext2 -b 1024 /dev/loop0 >/dev/null 2>&1
    mount -t ext2 /dev/loop0 /mnt
    umount /mnt
    losetup -d /dev/loop0
done

  it collapses with failed ioctl then BUG_ON(!bio).

  I think the original lo_done completion was more subtle and safe

no reason to make this atomic - only the idle thread does it

function.

[PATCH] x86_64: Calgary IOMMU - IOMMU abstractions

This patch creates a new interface for IOMMUs by adding a centralized
location for IOMMU allocation (for translation tables/apertures) and
IOMMU initialization.  In creating these, code was moved around for
abstraction, uniformity, and consiceness.

Take note of the move of the iommu_setup bootarg parsing code to
__setup.  This is enabled by moving back the location of the aperture
allocation/detection to mem init (which while ugly, was already the
location of the swiotlb_init).

While a slight departure from the previous patch, I belive this provides
the true intention of the previous versions of the patch which changed
this code.  It also makes the addition of the upcoming calgary code much
cleaner than previous patches.

early]
