      [PATCH] remove vm_area_struct.vm_raend · 55478b6c
      Andrew Morton authored
      Remove the unused vm_area_struct.vm_raend.
      
      If someone wants to tune per-VMA readaround then they can alter
      vma->vm_file->f_ra.ra_pages.

      [PATCH] ext2 synchronous mount fix · 7cc9ee3d
      Andrew Morton authored
      The optimisation for synchronous mounts was only correct for S_ISREG
      files.  Directories do not pass through generic_osync_inode() and we
      still need to synchronously write out their indirect blocks.

      [PATCH] tidier atomic check in mempool_alloc() · 36aed1f9
      Andrew Morton authored
      From Hugh.
      
      Be more explicit in the "can we sleep" test.  It doesn't change
      anything unless someone is performing __GFP_IO && !__GFP_WAIT
      allocations, which is nonsensical.

      [PATCH] provide a default super_block_operations · b88f83d5
      Andrew Morton authored
      A little cleanup suggested by Chris Mason or Al Viro.
      
      Quite a number of codepaths are testing whether a superblock has a
      non-null ->s_op pointer.  We can remove all those by making sure that
      all superblocks have a valid ->s_op.

      [PATCH] madvise_willneed() maximum readahead checking · 654107b9
      Andrew Morton authored
      madvise_willneed() currently has a very strange check on how much readahead
      it is prepared to do.
      
        It is based on the user's rss limit.  But this is usually enormous, and
        the user isn't necessarily going to map all that memory at the same time
        anyway.
      
        And the logic is wrong - it is comparing rss (which is in bytes) with
        `end - start', which is in pages.
      
        And it returns -EIO on error, which is not mentioned in the Open Group
        spec and doesn't make sense.
      
      
      This patch takes it all out and applies the same upper limit as is used in
      sys_readahead() - half the inactive list.
