there's a little confusion with ata vs. ide. the short 2008 story is that ata is a command set, ide is a programming interface. the history is much more complicated and riddled with backronyms like “pata.”
so i think it would be a good idea to at least make this change in sd(3) ; diffy -c sd /n/dump/2009/0212/sys/man/3/sd:21,36 - sd:21,39 .IR C , and by its unit number .IR u . - The controller naming convention for ATA(PI) units starts - with the first controller being named + The controller naming convention for legacy IDE units + names the first controller [etc.] i realize that it might be excessively annoying to change sdata.c to sdide.c, but even if that is too much i still think it would be a good idea to clarify things in the man page. after all, the ahci and mv50xx drivers also use the ata command set. objections? - erik
