Jeff Roberson 98082691bb - Make 'struct buf *buf' private to vfs_bio.c. Having a global variable ... 'buf' is inconvenient and has lead me to some irritating to discover bugs over the years. It also makes it more challenging to refactor the buf allocation system. - Move swbuf and declare it as an extern in vfs_bio.c. This is still not perfect but better than it was before. - Eliminate the unused ffs function that relied on knowledge of the buf array. - Move the shutdown code that iterates over the buf array into vfs_bio.c.
