Merge tag 'vfs-fix-ioctl-checking-3' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pull common SETFLAGS/FSSETXATTR parameter checking from Darrick Wong: "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. - 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" * tag 'vfs-fix-ioctl-checking-3' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: vfs: only allow FSSETXATTR to set DAX flag on files and dirs vfs: teach vfs_ioc_fssetxattr_check to check extent size hints vfs: teach vfs_ioc_fssetxattr_check to check project id info vfs: create a generic checking function for FS_IOC_FSSETXATTR vfs: create a generic checking and prep function for FS_IOC_SETFLAGS
