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
