OK, so I will go with the more "expressive" implementation that Jan suggested.

Callers that do NOT care about mount mark semantics will use the
wrapper:

vfs_create_notify(mnt, ...)
{
    vfs_create(...
    fsnotify_create(NULL,...
}

The two callers that do care about mount mark semantics (syscalls
and nfsd) will open code:

vfs_create(...
fsnotify_create(mnt,...

Hope that way works better for you.

Thanks,
Amir.
