Subject: Re: [PATCH 1/8] networking/fanotify: declare fanotify socket numbers

The patches did apply and build against next-20090910. I wrote a small user-
space utility for testing (attached); see how painless the socket interface 
is. The patches seem to be working well, except that some required 
functionality is missing still.

Currently, the CAP_NET_RAW capability is needed for being able to create 
watches. This seems too strict to me; I don't see why I shouldn't be able to 
watch my own files, or files which I have read access to (like inotify).

There are some actions like creating hardlinks in directories or removing 
files which don't trigger events. From a user point of view, I would prefer to 
receive those events as well. (I notice that it's not easy to to pass file 
descriptors to listeners for those events.)

Thanks,
Andreas
