Package: ntfs-3g
Version: 1:2016.2.22AR.1-3
My setup is as follows:
# cat /etc/fstab | grep -i ntfs
/dev/sda2 /media/my_data ntfs-3g
rw,user,noatime,discard,commit=300 0 0
# aptitude show util-linux | grep Version
Version: 2.28.1-1
# aptitude show ntfs-3g | grep Version
Version: 1:2016.2.22AR.1-3
# uname -a
Linux my_host_name 4.6.0-1-amd64 #1 SMP Debian 4.6.4-1 (2016-07-18)

Now:

# fstrim -v /media/my_data
/media/my_data/: 104,2 GiB (111868387328 bytes) trimmed
# fstrim -v /media/my_data
/media/my_data/: 104,2 GiB (111868387328 bytes) trimmed
Given that the current version of the ntfs-3g driver supports trimming,
and given that fstrim ran twice, I expect that the second command
reports "0 B (0 bytes) trimmed", contrary to the above.
Changing ntfs-3g to ntfs in /etc/fstab has no influence.
