On a different note, I'm reminded of the prefixes to members of certain structs. They're reminiscent of the days when C structs shared a single namespace. I'm thinking of the members of buffer_head like b_state. One great thing about b_state is that it makes grepping for examples of its use much easier. If it were called "state", it would be harder to figure out who's directly manipulating the state member of buffer_heads. -- --Ed L Cashin | PGP public key: ecashin@uga.edu | http://noserose.net/e/pgp/ -- Kernelnewbies: Help each other learn about the Linux kernel.
