[PATCH 03/10] ocfs2: don't opencode filemap_fdatawrite_range in ocfs2_journal_submit_inode_data_buffers

[Christoph Hellwig <hch@lst.de>]

Use filemap_fdatawrite_range instead of opencoding the logic using
filemap_fdatawrite_wbc.  There is a slight change in the conversion
as nr_to_write is now set to LONG_MAX instead of double the number
of the pages in the range.  LONG_MAX is the usual nr_to_write for
WB_SYNC_ALL writeback, and the value expected by lower layers here.
