    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.
