            Bug ID: 445468
           Summary: Cannot mount NTFS with the new ntfs3 module from Linux
                    5.15
           Product: dolphin
           Version: 21.08.3
          Platform: Archlinux Packages
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: dolphin-bugs-null at kde.org
          Reporter: herobrineak at gmail.com
                CC: kfm-devel at kde.org
  Target Milestone: ---

SUMMARY
If ntfs-3g is not installed, and Linux 5.15 ntfs3 (the new Paragon NTFS driver)
is present, Dolphin tries to mount NTFS partition, but mounts with unknown to
ntfs3 parameter - 'windows_names'


STEPS TO REPRODUCE
1.  Remove ntfs-3g FUSE driver
2.  Load ntfs3 module from Linux 5.15+
3.  Mount NTFS formatted partition via Dolphin

OBSERVED RESULT
Mount fails with:
An error occurred while accessing 'Home', the system responded: The requested
operation has failed: Error mounting /dev/sda4 at /run/media/linux/Data:
Unknown error when mounting /dev/sda4

EXPECTED RESULT
Mount partition and access like any other partition.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Arch Linux w/ Linux 5.15.1 from sources, and Linux 5.15.2
from repo
KDE Plasma Version: 5.23.3-1
KDE Frameworks Version: 5.87.0-1
Qt Version: 5.15.2+kde+r254-1
Dolphin Version: 21.08.3-1

ADDITIONAL INFORMATION
It appears that the new NTFS driver does not support 'windows_names' parameter.
Dolphin tries to mount with it. It appears that the new driver has no such
option and fails to mount.

>From dmesg after attempt to mount any NTFS partition via Dolphin:
[  194.448588] ntfs3: Unknown parameter 'windows_names'
