v2 fixes the following issues:
 - Fix up the cookie usage in uncached_readdir()
 - Changelog fixups for the second patch
 - .releasepage should use kmap_atomic() so that it can be called
   from all direct reclaim contexts.
 - Ensure that .releasepage also clears Pg_uptodate
 - Set/clear the Pg_private flag to ensure .releasepage gets called when
   appropriate.
 - Add a .invalidatepage to ensure truncate_inode_pages() works correctly
 - Ensure that the anonymous page that is generated by uncached_readdir()
   doesn't leak memory.

v3:
 - add the freepage() address space operation.
 - Dump the page locking
 - rewrite patch 'Fix a memory leak in nfs_readdir' to work with the new
   ->freepage() callback.

Linus Torvalds (1):
  Call the filesystem back whenever a page is removed from the page
    cache

Trond Myklebust (2):
  NFS: Ensure we use the correct cookie in nfs_readdir_xdr_filler
  NFS: Fix a memory leak in nfs_readdir
