`fatrace: Failed to add watch for .: No such device` on FUSE mount

[rbutoi]

On my ntfs-3g mounted external drive:

❯ sudo fatrace -c -t
fatrace: Failed to add watch for .: No such device

This works (great, I should add!) on ext4 drives -- any ideas here?

There's not much that fatrace can do if fanotify_mark() does not work on a particular file system. I would not expect this to ever work for FUSE file systems, as these are not under the kernel's control.

Thanks for the quick response and explanation!
