/*
* Select the desired position for the next block in a file. The file is
* logically divided into sections. The first section is composed of the
* direct blocks. Each additional section contains fs_maxbpg blocks.
*
* If no blocks have been allocated in the first section, the policy is to
* request a block in the same cylinder group as the inode that describes
* the file. Otherwise, the policy is to try to allocate the blocks
* contigously. The two fields of the ext2 inode extension (see
* ufs/ufs/inode.h) help this.
