2.5.41-mm1

[Andrew Morton <akpm@digeo.com>]

url: http://www.zip.com.au/~akpm/linux/patches/2.5/2.5.41/2.5.41-mm1/

- Some new work on the swap control algorithms. Most notably some
  code to dynamically clamp down on memory dirtiers if it appears
  likely that their activity will cause paging activity.

- Added Bill Irwin's hugetlb filesytem.  It exposes the hugetlb code
  via a mmap() interface.  Also Bill has enhanced sysv shared memory
  to allow that to be backed by hugetlbfs files.

- Included Al Viro's Orlov block allocator for ext2.  It speeds up
  operations against many-small-files-in-many-directories by just heaps.


+misc.patch

 Tiny bugfix

+get_bios_geometry.patch

 Some more 64-bit sector_t work from Peter.

+orlov-allocator.patch

 The Orlov block allocator.  Needs to be done for ext3 as well...

+hugetlb-prefault.patch
+ramfs-aops.patch
+hugetlb-header-split.patch
+hugetlbfs.patch
+hugetlb-shm.patch

 hugetlbfs and hugetlbfs-for-shm.

+remove-radix_tree_reserve.patch

 Remove radix_tree_reserve() - we don't actually need it (Hugh)

+raw-use-o_direct.patch

 Convert the raw driver to simply subvert the passed file* into using
 O_DIRECT reads and writes against the backing blockdev.  This
 unbreaks the raw driver.

+mapped-start-active.patch

 Start mapped pages on the active list, not the inactive list.
 They're going to go there anyway, and adding great blobs of
 mapped pages to the inactive list upsets things.

+rename-dirty_async_ratio.patch

 Rename /proc/sys/vm/dirty_async_ratio to just dirty_ratio

+auto-dirty-memory.patch

 Dynamically decrease the writer throttling threshold if there's
 a lot of mapped memory around -> prevents heavy writers from
 forcing paging activity - make them clean their own pagecache
 earlier instead.
