The XFS FAQ isn't an appropriate place for that tuning suggestion,
because it doesn't tune XFS. vm.vfs_cache_pressure tunes the page cache
and is file system agnostic. Thus you should remove that entry from the
FAQ. Perhaps a blog entry would be more appropriate, or a post to LKML,
so it gets archived. However, this is likely already posted somewhere,
as you can't be the first to run into this issue.
