Дим, а что тебе помешало процитировать оттуда буквально пару
строчек?

remove the raw driver

The raw driver used to provide direct unbuffered access to block
devices before O_DIRECT was invented. It has been obsolete for
more than a decade.

Или даже `man raw`:

NOTES
Rather than using raw devices applications should prefer open(2)
devices, such as /dev/sda1, with the O_DIRECT flag.

Всем (даже тем, кто этим никогда не интересовался) сразу было бы
понятно, что вместо /dev/raw* следует использовать O_DIRECT
