[PATCH] map multiple blocks for mpage_readpages()
This patch changes mpage_readpages() and get_block() to get the disk mapping
information for multiple blocks at the same time.
b_size represents the amount of disk mapping that needs to mapped. On the
successful get_block() b_size indicates the amount of disk mapping thats
actually mapped. Only the filesystems who care to use this information and
provide multiple disk blocks at a time can choose to do so.
No changes are needed for the filesystems who wants to ignore this.
