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

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

Second round of IIO cleanups for the 3.10 cycle

1) A nice little removal of the unwanted private pointer from
   struct iio_trigger.
2) Some clean up of the ad799x driver.
3) Couple of cleanups for the exynos_adc driver and some documentation.

A nice small set of worthy bits and bobs.

This patch fixes a regression introduced in v3.8-rc1 code where a failed
target_check_reservation() check in target_setup_cmd_from_cdb() was causing
an incorrect SAM_STAT_GOOD status to be returned during a WRITE operation
performed by an unregistered / unreserved iscsi initiator port.

This regression is only effecting iscsi-target due to a special case check
for TCM_RESERVATION_CONFLICT within iscsi_target_erl1.c:iscsit_execute_cmd(),
and was still correctly disallowing WRITE commands from backend submission
for unregistered / unreserved initiator ports, while returning the incorrect
SAM_STAT_GOOD status due to the missing SAM_STAT_RESERVATION_CONFLICT
assignment.

This regression was first introduced with:

commit de103c93aff0bed0ae984274e5dc8b95899badab
Author: Christoph Hellwig <hch@lst.de>
Date:   Tue Nov 6 12:24:09 2012 -0800

    target: pass sense_reason as a return value

Go ahead and re-add the missing SAM_STAT_RESERVATION_CONFLICT assignment
during a target_check_reservation() failure, so that iscsi-target code
sends the correct SCSI status.

All other fabrics using target_submit_cmd_*() with a RESERVATION_CONFLICT
call to transport_generic_request_failure() are not effected by this bug.

VM_POPULATE only has any effect when userspace plays racy games with
vmas by trying to unmap and remap memory regions that mmap or mlock are
operating on.

Also, the only effect of VM_POPULATE when userspace plays such games is
that it avoids populating new memory regions that get remapped into the
address range that was being operated on by the original mmap or mlock

staging: comedi: s626: remove the uint16_t casts of the bit values

There are a number of uint16_t casts used in the #define's of the
constant bit field values as well as the calls to DEBIreplace().
These cause a number of sparse warnings of the type:

warning: cast truncates bits from constant value (ffff1cff becomes 1cff)

Remove all of the casts and change the types of the parameters to
DEBIreplace from uin16_t to unsigned int. This fixes all the warnings.

Mask the addr that is or'ed with DEBI_CMD_RDWORD then written to the
P_DEBICMD register as well as the val written to the P_DEBIAD register
with 0xffff. The addr and val are only 16-bits but the registers are
32-bits.

Btrfs: fix space leak when we fail to reserve metadata space

Dave reported a warning when running xfstest 275.  We have been leaking delalloc
metadata space when our reservations fail.  This is because we were improperly
calculating how much space to free for our checksum reservations.  The problem
is we would sometimes free up space that had already been freed in another
thread and we would end up with negative usage for the delalloc space.  This
patch fixes the problem by calculating how much space the other threads would
have already freed, and then calculate how much space we need to free had we not
done the reservation at all, and then freeing any excess space.  This makes
xfstests 275 no longer have leaked space.  Thanks
