Yeah, that's really the right answer.  Having a common way of storing
attributes in struct kstat (and notified via struct iattr and
notify_change) is the right way for us to store some of these
filesystem-common flags, and would make a huge amount of sense.

I don't really view ths secure deletion and trash-bin support as
really being an ext4 feature, but really a generic feature which can
enhance multiple filesystems *including* ext4.  So it would be really
good idea to give these patches an airing on linux-fsdevel and
linux-kernel.
