GFS2: Implement iomap for block_map This patch implements iomap for block mapping, and switches the block_map function to use it under the covers. The additional IOMAP_F_BOUNDARY iomap flag indicates when iomap has reached a "metadata boundary" and fetching the next mapping is likely to incur an additional I/O. This flag is used for setting the bh buffer boundary flag. Signed-off-by: Bob Peterson <rpeterso@redhat.com> Signed-off-by: Andreas Gruenbacher <agruenba@redhat.com>
