fd2d1acfca fs-verity: add the hook for file ->open()
Add the fsverity_file_open() function, which prepares an fs-verity file
to be read from.  If not already done, it loads the fs-verity descriptor
from the filesystem and sets up an fsverity_info structure for the inode
which describes the Merkle tree and contains the file measurement.  It
also denies all attempts to open verity files for writing.

This commit also begins the include/linux/fsverity.h header, which
declares the interface between fs/verity/ and filesystems.

5585f2af73 fs-verity: add inode and superblock fields
Analogous to fs/crypto/, add fields to the VFS inode and superblock for
use by the fs/verity/ support layer:

- ->s_vop: points to the fsverity_operations if the filesystem supports
  fs-verity, otherwise is NULL.

- ->i_verity_info: points to cached fs-verity information for the inode
  after someone opens it, otherwise is NULL.

- S_VERITY: bit in ->i_flags that identifies verity inodes, even when
  they haven't been opened yet and thus still have NULL ->i_verity_info.

671e67b47e fs-verity: add Kconfig and the helper functions for hashing
Add the beginnings of the fs/verity/ support layer, including the
Kconfig option and various helper functions for hashing.  To start, only
SHA-256 is supported, but other hash algorithms can easily be added.

fe9918d3b2 fs: uapi: define verity bit for FS_IOC_GETFLAGS
Add FS_VERITY_FL to the flags for FS_IOC_GETFLAGS, so that applications
can easily determine whether a file is a verity file at the same time as
they're checking other file flags.  This flag will be gettable only;
FS_IOC_SETFLAGS won't allow setting it, since an ioctl must be used
instead to provide more parameters.

This flag matches the on-disk bit that was already allocated for ext4.

085771ec14 fs-verity: add UAPI header
Add the UAPI header for fs-verity, including two ioctls:

- FS_IOC_ENABLE_VERITY
- FS_IOC_MEASURE_VERITY

These ioctls are documented in the "User API" section of
Documentation/filesystems/fsverity.rst.

Examples of using these ioctls can be found in fsverity-utils
(https://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/fsverity-utils.git).

I've also written xfstests that test these ioctls
(https://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/xfstests-dev.git/log/?h=fsverity).

88c5083442 Wimplicit-fallthrough patches for 5.3-rc2
Hi Linus,
 
 Please, pull the following patches that mark switch cases where we are
 expecting to fall through. These patches are part of the ongoing efforts
 to enable -Wimplicit-fallthrough. Most of them have been baking in linux-next
 for a whole development cycle.
 
 Also, pull the Makefile patch that globally enables the
 -Wimplicit-fallthrough option.
 
 Finally, some missing-break fixes that have been tagged for -stable:
 
  - drm/amdkfd: Fix missing break in switch statement
  - drm/amdgpu/gfx10: Fix missing break in switch statement
 
 Notice that with these changes, we completely get rid of all the
 fall-through warnings in the kernel.
 
 Thanks

Merge tag 'libnvdimm-fixes-5.3-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm

Pull libnvdimm fixes from Dan Williams:
 "A collection of locking and async operations fixes for v5.3-rc2. These
  had been soaking in a branch targeting the merge window, but missed
  due to a regression hunt. This fixed up version has otherwise been in
  -next this past week with no reported issues.

  In order to gain confidence in the locking changes the pull also
  includes a debug / instrumentation patch to enable lockdep coverage
  for libnvdimm subsystem operations that depend on the device_lock for
  exclusion. As mentioned in the changelog it is a hack, but it works
  and documents the locking expectations of the sub-system in a way that
  others can use lockdep to verify. The driver core touches got an ack
  from Greg.

  Summary:

   - Fix duplicate device_unregister() calls (multiple threads competing
     to do unregister work when scheduling device removal from a sysfs
     attribute of the self-same device).

   - Fix badblocks registration order bug. Ensure region badblocks are
     initialized in advance of namespace registration.

Nine fixes: The most important core one is the dma_max_mapping_size
 fix that corrects the boot problem Gunter Roeck was having.  A couple
 of other driver only fixes are significant, like the cxgbi selector
 support addition, the alua 2 second delay and the fdomain build fix.

Pull drm fixes from Daniel Vetter:
 "Dave seems to collect an entire streak of things happening, so again
  me typing pull summary.

  Nothing nefarious here, most of the fixes are for new stuff or things
  users won't see. The amd-display patches are a bit different, and very
  much look like they should have at least some cc: stable tags. Might
  be amd is a bit too comfortable with their internal tree and not
  enough looking at upstream. Dave&me are looking into this, in case
  something needs rectified with process here.

  Also no intel fixes pull, but intel CI is general become rather good,
  still I guess expect a notch more for -rc3.

c6c84f78e2 block: fix max segment size handling in blk_queue_virt_boundary
We should only set the max segment size to unlimited if we actually
have a virt boundary.  Otherwise we accidentally clear that limit
when called from the SCSI midlayer, which always calls
blk_queue_virt_boundary, even if that mask is 0.

19a1c4092e fix the struct mount leak in umount_tree()
We need to drop everything we remove from the tree, whether
mnt_has_parent() is true or not.  Usually the bug manifests as a slow
memory leak (leaked struct mount for initramfs); it becomes much more
visible in mount_subtree() users, such as btrfs.  There we leak
a struct mount for btrfs superblock being mounted, which prevents
fs shutdown on subsequent umount.

Fixes: 56cbb429d9 ("switch the remnants of releasing the mountpoint away from fs_pin")
