major numbers for character and block files

[Jdamian]

lsdev reported me the major numbers for block and device files.

I saw that, in some cases, both block and character majors match, but in others, they don't.

My doubt is whether a same value (for example, 123) may be the major of block special files and the major of char special files but of TWO different drivers.

In other words, a major value is UNIQUE as block major (or as char major) OR as block and character major ?

Char Block Driver Class
188.....31..sdisk..disk
.31.....-1....tun.pseudo
