Aneesh Kumar K.V 17bc6c30cf vfs: Add no_nrwrite_index_update writeback control flag ...

If no_nrwrite_index_update is set we don't update nr_to_write and
address space writeback_index in write_cache_pages.  This change
enables a file system to skip these updates in write_cache_pages and do
them in the writepages() callback.  This patch will be followed by an
ext4 patch that make use of these new flags.
