No.  Take a good look at the instances.

	a) only one aberrant case cares about dentry, and for extremely
wrong reasons.  /proc/sys/ stuff.  ecryptfs, of course, will be happy
with any variant.
	b) few flags that are looked at are trivially mapped to new MAY_...

I have a patch series that does it, but it involves tons of fixing the
sysctl handling to be finished ;-/  And yes, we need sysctl to quit
doing the "I want to get ctl_table entry, so I'll do very painful search
by dentry every damn time" in any case - look at that code, it's far
too ugly to live.

IOW, consider this ->permission() API change NAKed.
