      The old form of designated initializers are obsolete: we need to replace them
      with the ISO C forms before 2.6.  Gcc has always supported both forms anyway.

      [PATCH] readahead optimisations · b6938a7b
      Andrew Morton authored
      Been looking at a workload which involves several processes which seek
      around and read from a large file.  There are a few problems:
      generic_file_lseek is bouncing i_sem around like mad, and readahead is
      doing lots of pointless pagecache probing.
      
      This patch addresses readahead.
      
      Presumably the change will be larger on machines which have higher
      bandwidth memory than my test box, of which there are many.
      
      This patch teaches readahead to detect the situation where no IO is
      actually being performed as a result of its actions.  Now, we don't
      want to sacrifice IO efficiency to save a bit of CPU, so the code is
      very cautious.  But eventually, after some tens of consecutive
      readahead attempts were found to perform no I/O at all, readahead will
      turn itself off.
      
      readahead will be turned on again when either generic_file_read() or
      filemap_nopage() get a pagecache miss.  The function
      handle_ra_thrashing() has been renamed to handle_ra_miss() to reflect
      its widened role.
      
      A performance bug in page_cache_readround() was fixed - if
      ra->next_size is zero, that function needs to leave it well alone,
      because next_size==0 is a magic value meaning that the file has just
      been opened and that readahead needs to get aggressive.  This change
      makes a `make dep' run at the same speed as in the 2.4 kernel.  It used
      to take 4x as long...
      
      `make dep' is an interesting test because it uses mmap to read the files.

      [PATCH] writeback scalability improvements · e64fa3db
      Andrew Morton authored
      The kernel has a number of problems wrt heavy write traffic to multiple
      spindles.  What keeps on happening is that all processes which are
      responsible for writeback get blocked on one of the queues and all the
      others fall idle.
      
      This happens in the balance_dirty_pages() path (balance_dirty() in 2.4)
      and in the page reclaim code, when a dirty page is found on the LRU.
      
      The latter is particularly bad because it causes "innocent" processes
      to be suspended for long periods due to the activity of heavy writers.
      
      The general idea is: the primary resource for writeback should be the
      process which is dirtying memory.  The secondary resource is the
      pdflush pool (although this is mainly for providing async writeback in
      the presence of light-moderate loads).  Add the final
      oh-gee-we-screwed-up resource for writeback is a caller to
      shrink_cache().
      
      This patch addresses the balance_dirty_pages() path.  This code was
      initially modelled on the 2.4 writeback scheme: throttled processes
      writeback all data regardless of its queue.  Instead, the patch changes
      it so that the balance_dirty_pages() caller only writes back pages
      which are dirty against the queue which that caller just dirtied.
      
      So the effect is a better allocation of writeback resources across the
      queues and increased parallelism.
      
      The per-queue writeback is implemented by using
      mapping->backing_dev_info as a search key during the walk across the
      superblocks and inodes.
      
      The patch also fixes an initialisation problem in
      block_dev.c:do_open(): it was setting up the blockdev's
      mapping->backing_dev_info too early, before the queue has been
      identified.
      
      Generally, this patch doesn't help much, because of the stalls in the
      page allocator.  I have a patch which mostly fixes that up, and taken
      together the kernel is achieving almost platter speed against six
      spindles, but only when the system has a small amount of memory.  More
      work is needed there.

      [PATCH] remove add_to_page_cache_unique() · cad46d66
      Andrew Morton authored
      A tasty patch from Hugh Dickens.  radix_tree_insert() fails if something
      was already present at the target index, so that error can be
      propagated back through add_to_page_cache().  Hence
      add_to_page_cache_unique() is obsolete.
      
      Hugh's patch removes add_to_page_cache_unique() and cleans up a bunch of
      stuff.
