    No. It would be fairly messy to implement in 2.4 because 2.4 does not have
    the per-inode radix trees for pagecache. The implementation would need to
    walk every page attached to the inode just to shoot down a single page.
    And all of it underneath the global pagecache lock.

    But it is certainly possible.
