First of all some necessary notes about UFS by it self: To avoid waste of disk
space the tail of file consists not from blocks (which is ordinary big enough,
16K usually), it consists from fragments(which is ordinary 2K).  When file is
growing its tail occupy 1 fragment, 2 fragments...  At some stage decision to
allocate whole block is made and all fragments are moved to one block.

How this situation was handled before:

  ufs_prepare_write
  ->block_prepare_write
    ->ufs_getfrag_block
      ->...
        ->ufs_new_fragments:

bh = sb_bread
bh->b_blocknr = result + i;
mark_buffer_dirty (bh);

This is wrong solution, because:

- it didn't take into consideration that there is another cache: "inode page
  cache"

- because of sb_getblk uses not b_blocknr, (it uses page->index) to find
  certain block, this breaks sb_getblk.

How this situation is handled now: we go though all "page inode cache", if
there are no such page in cache we load it into cache, and change b_blocknr.

With this patch a vma may define a vma->vm_ops->migrate function.  That
function may perform page migration on its own (some vmas may not contain page
structs and therefore cannot be handled by regular page migration.  Pages in a
vma may require special preparatory treatment before migration is possible
etc) .  Only mmap_sem is held when the migration function is called.  The
migrate() function gets passed two sets of nodemasks describing the source and
the target of the migration.  The flags parameter either contains

MPOL_MF_MOVE which means that only pages used exclusively by
the specified mm should be moved

or

MPOL_MF_MOVE_ALL which means that pages shared with other processes
should also be moved.

The migration function returns 0 on success or an error condition.  An error
condition will prevent regular page migration from occurring.

On its own this patch cannot be included since there are no users for this
functionality.  But it seems that the uncached allocator will need this
functionality at some point.

[PATCH] AOP_TRUNCATED_PAGE victims in read_pages() belong in the LRU

AOP_TRUNCATED_PAGE victims in read_pages() belong in the LRU

Nick Piggin rightly pointed out that the introduction of AOP_TRUNCATED_PAGE
to read_pages() was wrong to leave A_T_P victim pages in the page cache but
not put them in the LRU.  Failing to do so hid them from the VM.

A_T_P just means that the aop method unlocked the page rather than
performing IO.  It would be very rare that the page was truncated between
the unlock and testing A_T_P.  So we leave the pages in the LRU for likely
reuse soon rather than backing them back out of the page cache.  We do this
by matching the behaviour before the A_T_P introduction which added pages
to the LRU regardless of what ->readpage() did.

This doesn't include the unrelated cleanup in Nick's initial fix which
changed read_pages() to return void to match its only caller's behaviour of
ignoring errors.

It never dereferenced a user pointer, the "->" operator was to an array

performance penalty associated with it.
