Hi Linus,

Here's a patch series that sets up common parameter checking functions
for the FS_IOC_SETFLAGS and FS_IOC_FSSETXATTR ioctl implementations.
The goal here is to reduce the amount of behaviorial variance between
the filesystems where those ioctls originated (ext2 and XFS,
respectively) and everybody else.

The branch merges cleanly against this morning's HEAD and survived an
overnight run of xfstests.  The merge was completely straightforward, so
please let me know if you run into anything weird.

  vfs: only allow FSSETXATTR to set DAX flag on files and dirs (2019-07-01 08:25:36 -0700)

----------------------------------------------------------------
New for 5.3:
- Standardize parameter checking for the SETFLAGS and FSSETXATTR ioctls
  (which were the file attribute setters for ext4 and xfs and have now
  been hoisted to the vfs)
- Only allow the DAX flag to be set on files and directories.

----------------------------------------------------------------
Darrick J. Wong (5):
      vfs: create a generic checking and prep function for FS_IOC_SETFLAGS
      vfs: create a generic checking function for FS_IOC_FSSETXATTR
      vfs: teach vfs_ioc_fssetxattr_check to check project id info
      vfs: teach vfs_ioc_fssetxattr_check to check extent size hints
      vfs: only allow FSSETXATTR to set DAX flag on files and dirs
