So far, I have only implemented OPEN intents. In the future, it may
prove to be useful to add intents for other operations (I know the
Lustre project in particular is keen to do this) in order to optimize
away unnecessary file permission checks, and other such things.
The patches presented now differ from those presented in May in that
I've tried to take into account both Linus' and Al Viro's comments.
The strategy is therefore to make use of the 'struct nameidata',
when it exists, and feed that down to the filesystem. The actual
intent information is then included as a union in the nameidata.
Cheers,
Trond
