[PATCH] ext3: multi-block get_block()

[PATCH] ext3: multi-block get_block()

Mingming Cao recently added multi-block allocation support for ext3,
currently used only by DIO.  I added support to map multiple blocks for
mpage_readpages().  This patch add support for ext3_get_block() to deal
with multi-block mapping.  Basically it renames ext3_direct_io_get_blocks()
as ext3_get_block().
