Merge tag 'libnvdimm-for-5.17' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm

Pull dax and libnvdimm updates from Dan Williams:
"The bulk of this is a rework of the dax_operations API after
discovering the obstacles it posed to the work-in-progress DAX+reflink
support for XFS and other copy-on-write filesystem mechanics.

Primarily the need to plumb a block_device through the API to handle
partition offsets was a sticking point and Christoph untangled that
dependency in addition to other cleanups to make landing the
DAX+reflink support easier.

The DAX_PMEM_COMPAT option has been around for 4 years and not only
are distributions shipping userspace that understand the current
configuration API, but some are not even bothering to turn this option
on anymore, so it seems a good time to remove it per the deprecation
schedule. Recall that this was added after the device-dax subsystem
moved from /sys/class/dax to /sys/bus/dax for its sysfs organization.
All recent functionality depends on /sys/bus/dax.

Some other miscellaneous cleanups and reflink prep patches are
included as well.

Summary:

- Simplify the dax_operations API:

- Eliminate bdev_dax_pgoff() in favor of the filesystem
maintaining and applying a partition offset to all its DAX iomap
operations.

- Remove wrappers and device-mapper stacked callbacks for
->copy_from_iter() and ->copy_to_iter() in favor of moving
block_device relative offset responsibility to the
dax_direct_access() caller.

- Remove the need for an @bdev in filesystem-DAX infrastructure

- Remove unused uio helpers copy_from_iter_flushcache() and
copy_mc_to_iter() as only the non-check_copy_size() versions are
used for DAX.

- Prepare XFS for the pending (next merge window) DAX+reflink support

- Remove deprecated DEV_DAX_PMEM_COMPAT support

- Cleanup a straggling misuse of the GUID api"

Merge tag 'erofs-for-5.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/xiang/erofs

Pull erofs updates from Gao Xiang:
"In this cycle, tail-packing data inline for compressed files is now
supported so that tail pcluster can be stored and read together with
inode metadata in order to save data I/O and storage space.

In addition to that, to prepare for the upcoming subpage, folio and
fscache features, we also introduce meta buffers to get rid of
erofs_get_meta_page() since it was too close to the page itself.

In addition, in order to show supported kernel features and control
sync decompression strategy, new sysfs nodes are introduced in this
cycle as well.

Summary:

- add sysfs interface and a sysfs node to control sync decompression

- add tail-packing inline support for compressed files

- get rid of erofs_get_meta_page()"

erofs: add on-disk compressed tail-packing inline support

Introduces erofs compressed tail-packing inline support.

This approach adds a new field called `h_idata_size' in the
per-file compression header to indicate the encoded size of
each tail-packing pcluster.

At runtime, it will find the start logical offset of the tail
pcluster when initializing per-inode zmap and record such
extent (headlcn, idataoff) information to the in-memory inode.
Therefore, follow-on requests can directly recognize if one
pcluster is a tail-packing inline pcluster or not.
