 "Three cleanup patches, no behavior changes"

  tomoyo: remove unused function declaration
  tomoyo: refactor deprecated strncpy
  tomoyo: add format attributes to functions

In current packed virtqueue implementation, the avail_wrap_counter won't
flip, in the case when the driver supplies a descriptor chain with a
length equals to the queue size; total_sg == vq->packed.vring.num.

Let’s assume the following situation:
vq->packed.vring.num=4
vq->packed.next_avail_idx: 1
vq->packed.avail_wrap_counter: 0

Then the driver adds a descriptor chain containing 4 descriptors.

We expect the following result with avail_wrap_counter flipped:
vq->packed.next_avail_idx: 1
vq->packed.avail_wrap_counter: 1

But, the current implementation gives the following result:
vq->packed.next_avail_idx: 1
vq->packed.avail_wrap_counter: 0

To reproduce the bug, you can set a packed queue size as small as
possible, so that the driver is more likely to provide a descriptor
chain with a length equal to the packed queue size. For example, in
qemu run following commands:
sudo qemu-system-x86_64 \
-enable-kvm \
-nographic \
-kernel "path/to/kernel_image" \
-m 1G \
-drive file="path/to/rootfs",if=none,id=disk \
-device virtio-blk,drive=disk \
-drive file="path/to/disk_image",if=none,id=rwdisk \
-device virtio-blk,drive=rwdisk,packed=on,queue-size=4,\
indirect_desc=off \
-append "console=ttyS0 root=/dev/vda rw init=/bin/bash"

Inside the VM, create a directory and mount the rwdisk device on it. The
rwdisk will hang and mount operation will not complete.

This commit fixes the wrap counter error by flipping the
packed.avail_wrap_counter, when start of descriptor chain equals to the
end of descriptor chain (head == i).

We try to build affinity mask via create_affinity_masks()
unconditionally which may lead several issues:

- the affinity mask is not used for parent without affinity support
  (only VDUSE support the affinity now)
- the logic of create_affinity_masks() might not work for devices
  other than block. For example it's not rare in the networking device
  where the number of queues could exceed the number of CPUs. Such
  case breaks the current affinity logic which is based on
  group_cpus_evenly() who assumes the number of CPUs are not less than
  the number of groups. This can trigger a warning[1]:

	if (ret >= 0)
		WARN_ON(nr_present + nr_others < numgrps);

Fixing this by only build the affinity masks only when

- Driver passes affinity descriptor, driver like virtio-blk can make
  sure to limit the number of queues when it exceeds the number of CPUs
- Parent support affinity setting config ops

This help to avoid the warning. More optimizations could be done on
top.

Currently, the virtio core will perform a dma operation for each
buffer. Although, the same page may be operated multiple times.

This patch, the driver does the dma operation and manages the dma
address based the feature premapped of virtio core.

This way, we can perform only one dma operation for the pages of the
alloc frag. This is beneficial for the iommu device.

Now we add a case where we skip dma unmap, the vq->premapped is true.

We can't just rely on use_dma_api to determine whether to skip the dma
operation. For convenience, I introduced the "do_unmap". By default, it
is the same as use_dma_api. If the driver is configured with premapped,
then do_unmap is false.

So as long as do_unmap is false, for addr of desc, we should skip dma
unmap operation.

This just work when the use_dma_api is true. If the use_dma_api is false,

Pull f2fs updates from Jaegeuk Kim:
 "In this cycle, we don't have a highlighted feature enhancement, but
  mostly have fixed issues mainly in two parts: 1) zoned block device,
  and 2) compression support.

  For zoned block device, we've tried to improve the power-off recovery
  flow as much as possible. For compression, we found some corner cases
  caused by wrong compression policy and logics. Other than them, there
  were some reverts and stat corrections.

  Bug fixes:
   - use finish zone command when closing a zone
   - check zone type before sending async reset zone command
   - fix to assign compress_level for lz4 correctly
   - fix error path of f2fs_submit_page_read()
   - don't {,de}compress non-full cluster
   - send small discard commands during checkpoint back
   - flush inode if atomic file is aborted
   - correct to account gc/cp stats

  And, there are minor bug fixes, avoiding false lockdep warning, and
  clean-ups"

Pull probes updates from Masami Hiramatsu:

 - kprobes: use struct_size() for variable size kretprobe_instance data
   structure.

 - eprobe: Simplify trace_eprobe list iteration.

 - probe events: Data structure field access support on BTF argument.

     - Update BTF argument support on the functions in the kernel
       loadable modules (only loaded modules are supported).

     - Move generic BTF access function (search function prototype and
       get function parameters) to a separated file.

     - Add a function to search a member of data structure in BTF.

     - Support accessing BTF data structure member from probe args by
       C-like arrow('->') and dot('.') operators. e.g.
          't sched_switch next=next->pid vruntime=next->se.vruntime'

     - Support accessing BTF data structure member from $retval. e.g.
          'f getname_flags%return +0($retval->name):string'

     - Add string type checking if BTF type info is available. This will
       reject if user specify ":string" type for non "char pointer"
       type.

     - Automatically assume the fprobe event as a function return event
       if $retval is used.

 - selftests/ftrace: Add BTF data field access test cases.
