I tried to integrate all the suggestions Steve gave. The purpose of the patch is to change function gfs2_alloc_block (allocate either a dinode block or an extent of data blocks) to a more generic gfs2_alloc_blocks function that can allocate both a dinode _and_ an extent of data blocks in the same call. This will ultimately help us create a multi-block reservation scheme to reduce file fragmentation. This patch moves more toward a generic multi-block allocator that takes a pointer to the number of data blocks to allocate, plus whether or not to allocate a dinode. In theory, it could be called to allocate (1) a single dinode block, (2) a group of one or more data blocks, or (3) a dinode plus several data blocks.
