    True. That should read:


    When we remount a filesystem or invalidate a block device which has a
    mounted filesystem we call shrink dcache_sb which currently:
    - moves a collection of dentries to the end of the dentry_unused list
    - calls prune_dcache to prune that number of dentries.

    but the patch is still valid.

    Any objections to it going in to -mm and maybe .20 ??

    Thanks,
    NeilBrown
