      Revert "lockdep: check that no locks held at freeze time" · dbf520a9

      This reverts commit 6aa97070.
      
      Commit 6aa97070 ("lockdep: check that no locks held at freeze time")
      causes problems with NFS root filesystems.  The failures were noticed on
      OMAP2 and 3 boards during kernel init:
      
        [ BUG: swapper/0/1 still has locks held! ]

      Although the rootfs mounts, the system is unstable.  Here's a transcript
      from a PM test:

      Here's what the test log should look like:

      Mailing list discussion is here:

      Deal with this for v3.9 by reverting the problem commit, until folks can
      figure out the right long-term course of action.

       "This includes the bug-fix for a >= v3.8-rc1 regression specific to
        iscsi-target persistent reservation conflict handling (CC'ed to
        stable), and a tcm_vhost patch to drop VIRTIO_RING_F_EVENT_IDX usage
        so that in-flight qemu vhost-scsi-pci device code can detect the
        proper vhost feature bits.
      
        Also, there are two more tcm_vhost patches still being discussed by
        MST and Asias for v3.9 that will be required for the in-flight qemu
        vhost-scsi-pci device patch to function properly, and that should
        (hopefully) be the last target fixes for this round."

      The Adam Belay's e-mail address in MAINTAINERS under PNP SUPPORT
      is not valid any more and I started to maintain that code in the

      rbd: don't zero-fill non-image object requests · 6e2a4505
      Alex Elder 提交于
      A result of ENOENT from a read request for an object that's part of
      an rbd image indicates that there is a hole in that portion of the
      image.  Similarly, a short read for such an object indicates that
      the remainder of the read should be interpreted a full read with
      zeros filling out the end of the request.
      
      This behavior is not correct for objects that are not backing rbd
      image data.  Currently rbd_img_obj_request_callback() assumes it
      should be done for all objects.
      
      Change rbd_img_obj_request_callback() so it only does this zeroing
      for image objects.  Encapsulate that special handling in its own
      function.  Add an assertion that the image object request is a bio
      request, since we assume that (and we currently don't support any
      other types).
      
      This resolves a problem identified here:
          http://tracker.ceph.com/issues/4559
      
      The regression was introduced by bf0d5f50.

      Pull btrfs fixes from Chris Mason:
       "We've had a busy two weeks of bug fixing.  The biggest patches in here
        are some long standing early-enospc problems (Josef) and a very old
        race where compression and mmap combine forces to lose writes (me).
        I'm fairly sure the mmap bug goes all the way back to the introduction
        of the compression code, which is proof that fsx doesn't trigger every
        possible mmap corner after all.
      
        I'm sure you'll notice one of these is from this morning, it's a small
        and isolated use-after-free fix in our scrub error reporting.  I
        double checked it here."
