      [PATCH] dynamic request allocation · ac062f74
      Jens Axboe authored
      This patch adds dynamic allocation of request structures. Right now we
      are reserving 256 requests per initialized queue, which adds up to quite
      a lot of memory for even a modest number of queues. For the quoted 4000
      disk systems, it's a disaster.
      
      Instead, we mempool 4 requests per queue and put an upper limit on the
      number of requests that we will put in-flight as well. I've kept the 128
      read/write max in-flight limit for now. It is trivial to experiement
      with larger queue sizes now, but I want to change one thing at the time
      (the truncate scenario doesn't look all that good with a huge number of
      requests, for instance).
      
      Patch has been in -mm for a while, I'm running it here against stock 2.5
      as well. Additionally, it actually kills quite a bit of code as well

      [PATCH] shrink deadline hash size · 0975ab2a
      Jens Axboe authored
      Limit deadline hash to 32 entries instead of 1024. This has been benched
      and profiled extensively and shows no increased system time.
      
      Also, move "hot" entries to the front of the list.

      [PATCH] bio_endio() increments bio->bi_sector · 04421ade
      Jens Axboe authored
      increment bi_sector in bio_endio() so make_request_fn drivers don't
      have to do this accounting themselves.
