Pull block fixes from Jens Axboe:
 "Alright, this time from 10K up in the air.

  Collection of fixes that have been queued up since the merge window
  opened, hence postponed until later in the cycle.  The pull request
  contains:

   - A bunch of fixes for the xen blk front/back driver.

   - A round of fixes for the new IBM RamSan driver, fixing various
     nasty issues.

   - Fixes for multiple drives from Wei Yongjun, bad handling of return
     values and wrong pointer math.

   - A fix for loop properly killing partitions when being detached."

Pull ceph fix from Sage Weil:
 "This fixes a regression introduced during the last merge window when
  mapping non-existent images."

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client:
  rbd: don't zero-fill non-image object requests

rbd: don't zero-fill non-image object requests

2013-03-29T18:32:07+00:00

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 bf0d5f503dc11d6314c0503591d258d60ee9c944.

rsxx: enable error return of rsxx_eeh_save_issued_dmas()

2013-03-26T20:48:11+00:00

Commit d8d595df introduced a bug where we did not check for a NULL
return from kmalloc(). Make rsxx_eeh_save_issued_dmas() return an
error for that case, and make the callers handle that.

 "These patches have mostly been baking for a few months; sorry I didn't
  get them in during the merge window.  They're all bug fixes, except
  for the addition of the SMART log and the addition to MAINTAINERS."

NVMe: Add namespaces with no LBA range feature

2013-03-22T18:50:23+00:00

The LBA Range Type feature is optional in the NVMe specification,
so we should continue with adding namespaces for controllers that do
not implement this feature.

cciss: fix invalid use of sizeof in cciss_find_cfgtables()

2013-03-22T18:22:49+00:00

sizeof() when applied to a pointer typed expression gives the
size of the pointer, not that of the pointed data.
