Subject: [PATCH v2 0/6] fs/ntfs3: Use new mount api and change some opts

This series modify ntfs3 to use new mount api as Christoph Hellwig
wish for. And also it must be done at some point.
lore.kernel.org/linux-fsdevel/20210810090234.GA23732@....de/

It also modify mount options noatime (not needed). Make new alias for
nls because kernel is changing to use it as described in here
lore.kernel.org/linux-fsdevel/20210808162453.1653-1-pali@...nel.org/

Modify mount opt no_acl_rules so we can use new mount api feature so
new one is (no)acl_rules. I'm open to suggestion what should we call
this if this is not good.

I did testing some testing and there seems to be unnecesarry remount
flags. Probably copy paste from another driver. Christoph also
suggested that maybe we should not let user remount with every
possible parameter, but for now comment can do. This can be addressed
later imo. Of course we can talk about it and I will do it if we have
solution.

Xfstests also show same errors than before this patch series. We will
of course wait Paragon's results also because they might have some
tests that I cannot yeat run.

Hopefully Konstantin will also comment in some point. And we have to
remember that we do not even have v28 in review process which this is
based on. So no rush to review. I just feeled that this is quite
ready and also that Konstantin can comment newer version so thats why
"already" patch series v2.

Offtopic:
I have also started to make shutdown protocol to ntfs3 driver so that
we can use that somepoint for testing with xfstests. 

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
