Hi everyone! I'm regular Arch-linux user and have been using your driver for a while (https://aur.archlinux.org/packages/ntfs3-dkms/). There are a lot of users who tested this patch and some of them, like me, have complaints. I faced stalling of a kthread with some ntfs functions in a stacktrace while rsyncing one NTFS partition (SATA) to another (USB HDD) (https://aur.archlinux.org/packages/ntfs3-dkms/#comment-818819): [ 5529.507567] INFO: task kworker/0:1:18 blocked for more than 1105 seconds.

Also adding ntfs3 partition (1.4TB) to fstab makes booting much slower: I see two lines in console (systemd version and some other line) and HDD led constantly flickering (seems like ntfs3 is traversing entire partition) (https://aur.archlinux.org/pkgbase/ntfs3-dkms/edit-comment/?comment_id=818673).
