Currently, Dazuko only supports "Open" and "Exec" events on 2.6 using
LSM.
Since dazuko registers the "inode_permission" hook, all the events
which are
generated are because of open or exec, which are what we need. Can you

expand on what you mean by "many" events ? Also, the context switches
happen
only when the user registers for the dev directory, so I guess they do
not come 
into the picture unless the user actually wants to listen to them.
