Subject: Re: [PATCH v26 00/10] NTFS read-write driver GPL implementation by
 Paragon Software

Hello!

I would like to remind that there are still two open questions about
this ntfs driver which needs to be resolved by vfs maintainers (Al?)
prior merging / accepting this driver into kernel tree.

1) Should this new ntfs driver use and implement old FAT ioctl calls?
These ioctls are added in patch: Add file operations and implementation.
First time I wrote about them in email:
https://lore.kernel.org/linux-fsdevel/20200921133647.3tczqm5zfvae6q6a@pali/

2) Should kernel have two ntfs drivers? And if yes, how they would
interact to userspace? Both Christoph and me think that not, see email:
