While this is a good start, I would suggest that in your proposal you go
into more details, in particular the first part - the inotify interface.
You should research it some more and ideally outline what changes you
want to implement where and what the approach you'll take - or at least
what options there are (with technical details of each).

We generally also like to see prior experience/code in proposals. So
please add some reference to some code/patch/etc that you have written -
and ideally ended up in some open source project. Alternatively it's
always an option to go through our bugtracker and maybe fix an easy bug
or two.
