Fstrim is not working anymore for NTFS partition

I tried to run fstrim on a NTFS partition but it returns the following error:

fstrim: /media/windows: FITRIM ioctl failed: Device or resource busy

I have checked dmesg and I don't see any error pertaining to the partition.
When I tried downgrading linux from 5.10.3 to 5.9.14, fstrim works.

it may be related to removed ntfs driver support from kernel: https://github.com/archlinux/svntogit-p … 5eb9b7203a

But doesn't NTFS-3G supports fstrim? Removal of the module should not affect NTFS-3G, right?

I have rebuild the kernel with NTFS module enabled but the same error occurs. There must be some changes in 5.10 that breaks fstrim for NTFS.

I encountered the same issue with linux 5.10.4. I was wondering if you have submitted a bug report to the kernel maintainer?
