No error when inotify_add_watch(/an/NFS/file)

Dear Experts,

NFS doesn't work with inotify (and it looks like it can't, certainly not before NFS v4.1). However, if I give an NFS filename to inotify_add_watch(), I don't get an error.

If it indicated an error in this case then I could easily fall back to some sort of polling. Without an error, I need some other way to detect NFS (and any other non-inotify-compatible filesystems).

Any thoughts?


Phil.
