      mm/fs: cleancache documentation · 4fe4746a
      Dan Magenheimer 提交于
      This patchset introduces cleancache, an optional new feature exposed
      by the VFS layer that potentially dramatically increases page cache
      effectiveness for many workloads in many environments at a negligible
      cost.  It does this by providing an interface to transcendent memory,
      which is memory/storage that is not otherwise visible to and/or directly
      addressable by the kernel.
      
      Instead of being discarded, hooks in the reclaim code "put" clean
      pages to cleancache.  Filesystems that "opt-in" may "get" pages
      from cleancache that were previously put, but pages in cleancache are
      "ephemeral", meaning they may disappear at any time. And the size
      of cleancache is entirely dynamic and unknowable to the kernel.
      Filesystems currently supported by this patchset include ext3, ext4,
      btrfs, and ocfs2.  Other filesystems (especially those built entirely
      on VFS) should be easy to add, but should first be thoroughly tested to
      ensure coherency.
      
      Details and a FAQ are provided in Documentation/vm/cleancache.txt
      
      This first patch of eight in this cleancache series only adds two
      new documentation files.

      numa: update Documentation/vm/numa, add memoryless node info · b9498bfe
      Lee Schermerhorn 提交于
      Kamezawa Hiroyuki requested documentation for the numa_mem_id() and slab
      related changes.  He suggested Documentation/vm/numa for this
      documentation.  Looking at this file, it seems to me to be hopelessly out
      of date relative to current Linux NUMA support.  At the risk of going down
      a rathole, I have made an attempt to rewrite the doc at a slightly higher
      level [I think] and provide pointers to other in-tree documents and
      out-of-tree man pages that cover the details.
      
      Let the games begin.
