[PATCH v3 0/9] fs/ntfs3: Use new mount api and change some opts

[Kari Argillander <kari.argillander@gmail.com>]

See V2 if you want:
lore.kernel.org/ntfs3/20210819002633.689831-1-kari.argillander@gmail.com

NLS change is now blocked when remounting. Christoph also suggest that
we block all other mount options, but I have tested a couple and they
seem to work. I wish that we do not block any other than NLS because
in theory they should work. Also Konstantin can comment about this.

I have not include reviewed/acked to patch "Use new api for mounting"
because it change so much. I have also included three new patch to this
series:
	- Convert mount options to pointer in sbi
		So that we do not need to initiliaze whole spi in 
		remount.
	- Init spi more in init_fs_context than fill_super
		This is just refactoring. (Series does not depend on this)
	- Show uid/gid always in show_options()
		Christian Brauner kinda ask this. (Series does not depend
		on this)

Series is ones again tested with kvm-xfstests. Every commit is build
tested.

v3:
	- Add patch "Convert mount options to pointer in sbi"
	- Add patch "Init spi more in init_fs_context than fill_super"
	- Add patch "Show uid/gid always in show_options"
	- Patch "Use new api for mounting" has make over
	- NLS loading is not anymore possible when remounting
	- show_options() iocharset printing is fixed
	- Delete comment that testing should be done with other
	  mount options.
	- Add reviewed/acked-tags to 1,2,6,8 
	- Rewrite this cover
v2:
	- Rewrite this cover leter
	- Reorder noatime to first patch
	- NLS loading with string
	- Delete default_options function
	- Remove remount flags
	- Rename no_acl_rules mount option
	- Making code cleaner
	- Add comment that mount options should be tested
