      [PATCH] cpuset memory spread: slab cache filesystems · 4b6a9316
      Paul Jackson 提交于
      Mark file system inode and similar slab caches subject to SLAB_MEM_SPREAD
      memory spreading.
      
      If a slab cache is marked SLAB_MEM_SPREAD, then anytime that a task that's
      in a cpuset with the 'memory_spread_slab' option enabled goes to allocate
      from such a slab cache, the allocations are spread evenly over all the
      memory nodes (task->mems_allowed) allowed to that task, instead of favoring
      allocation on the node local to the current cpu.
      
      The following inode and similar caches are marked SLAB_MEM_SPREAD:
      
          file                               cache

      The choice of which slab caches to so mark was quite simple.  I marked
      those already marked SLAB_RECLAIM_ACCOUNT, except for fs/xfs, dentry_cache,
      inode_cache, and buffer_head, which were marked in a previous patch.  Even
      though SLAB_RECLAIM_ACCOUNT is for a different purpose, it marks the same
      potentially large file system i/o related slab caches as we need for memory
      spreading.
      
      Given that the rule now becomes "wherever you would have used a
      SLAB_RECLAIM_ACCOUNT slab cache flag before (usually the inode cache), use
      the SLAB_MEM_SPREAD flag too", this should be easy enough to maintain.
      Future file system writers will just copy one of the existing file system
      slab cache setups and tend to get it right without thinking.

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
