090d2b185d [PATCH] read_mapping_page for address space
Add read_mapping_page() which is used for callers that pass
mapping->a_ops->readpage as the filler for read_cache_page.  This removes
some duplication from filesystem code.

1b1dcc1b57 [PATCH] mutex subsystem, semaphore to mutex: VFS, ->i_sem
This patch converts the inode semaphore to a mutex. I have tested it on
XFS and compiled as much as one can consider on an ia64. Anyway your
luck with it might be different.

2a6fc4e1b0 NTFS: Fix ntfs_attr_make_non_resident() to update the vfs inode i_blocks
which is zero for a resident attribute but should no longer be zero

8925d4f0d3 NTFS: Change ntfs_attr_make_non_resident to take the attribute value size
as an extra parameter.  This is needed since we need to know the size
      before we can map the mft record and our callers always know it.  The
      reason we cannot simply read the size from the vfs inode i_size is
      that this is not necessarily uptodate.  This happens when
      ntfs_attr_make_non_resident() is called in the ->truncate call path.

  return LCN_ENOENT when there is no runlist and the allocated size is
  zero.
- Fix load_attribute_list() to handle the case of a NULL runlist.

4757d7dff6 NTFS: Change ntfs_map_runlist_nolock() to only decompress the mapping pairs
if the requested vcn is inside it.  Otherwise we get into problems
      when we try to map an out of bounds vcn because we then try to map
      the already mapped runlist fragment which causes
      ntfs_mapping_pairs_decompress() to fail and return error.  Update
      ntfs_attr_find_vcn_nolock() accordingly.

1da177e4c3 Linux-2.6.12-rc2
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!
