[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().
