Make in-core inode bitmap static part of superblock info structure. Print a warning when mounting a BFS filesystem created with "-N 512" option as only 510 files can be created in the root directory. Make the kernel messages more uniform. Update the 'prefix' passed to bfs_dump_imap() to match the current naming of operations. White space and comments cleanup.
