      [PATCH] use smp_mb/wmb/rmb where possible · d59dd462
      akpm@osdl.org authored
      Replace a number of memory barriers with smp_ variants.  This means we won't
      take the unnecessary hit on UP machines.

      [PATCH] mempool: simplify alloc · 20a77776
      Nick Piggin authored
      Mempool is pretty clever.  Looks too clever for its own good :) It
      shouldn't really know so much about page reclaim internals.
      - don't guess about what effective page reclaim might involve.
      - don't randomly flush out all dirty data if some unlikely thing
        happens (alloc returns NULL). page reclaim can (sort of :P) handle
      I think the main motivation is trying to avoid pool->lock at all costs.
      However the first allocation is attempted with __GFP_WAIT cleared, so it
      will be 'can_try_harder' if it hits the page allocator.  So if allocation
      still fails, then we can probably afford to hit the pool->lock - and what's
      the alternative?  Try page reclaim and hit zone->lru_lock?
      A nice upshot is that we don't need to do any fancy memory barriers or do
      (intentionally) racy access to pool-> fields outside the lock.

      [PATCH] mempool: NOMEMALLOC and NORETRY · b84a35be
      Nick Piggin authored
      Mempools have 2 problems.
      The first is that mempool_alloc can possibly get stuck in __alloc_pages
      when they should opt to fail, and take an element from their reserved pool.
      The second is that it will happily eat emergency PF_MEMALLOC reserves
      instead of going to their reserved pools.
      Fix the first by passing __GFP_NORETRY in the allocation calls in
      mempool_alloc.  Fix the second by introducing a __GFP_MEMPOOL flag which
      directs the page allocator not to allocate from the reserve pool.

      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!
