...k this is a bug? When I do the same on an ext4 partition I get different behavior: the output shows 0 B trimmed and it does is instantaneously when I run it a 2nd time. After contacting the fstrim developer, he stated that the userspace part (fstrim) does only one thing and it is invoke an ioctl (FITRIM); it is the job of the filesystem to properly implement this.
Supporting data
----------------
Example on a btrfs partition:
The 1st time:
% time sudo fstrim -v /
/: 5.2 GiB (5575192576 bytes) trimmed
sudo fstrim -v / 0.00s user 0.05s system 2% cpu 2.084 total
The 2nd time:

Impossible or Possible to Securely Erase File on Btrfs?
Hi,
After reading through the btrfs documentation I''m curious to know if
it''s possible to ever securely erase a file from a btrfs filesystem (or
ZFS for that matter). On non-COW filesystems atop regular HDDs one can
simply overwrite the file with zeros or random data using dd or some
other tool and rest assured that the blocks which contained the
sensitive information have
