Yeah, that would be just as good, really. Maybe even better.
Mark Lord wrote (later on):
Instead, software has to search everything inside /sys/block/
looking for a "dev" file whose contents match,
rather than just trying to access something like this:
/sys/block/8:1/start
or
/sys/block/majors/8/minors/1/start
Or any one of a number of similar ways to arrange it.
..
It shouldn't be under /sys/block... there are enough many things that
scan /sys/block and assume any directory underneath it has the current
format.
..
So long as we only add things, and not remove them, then any software
that scans /sys/block/ shouldn't care, really.
But yes, it could go elsewhere, too.
Perhaps a /sys/dev/ directory, populated with symbolic links
(or hard links?) back to the /sys/block/ entries, something like this:
/sys/dev/block/8:0 -> ../../../block/sda
/sys/dev/block/8:1 -> ../../../block/sda/sda1
/sys/dev/block/8:2 -> ../../../block/sda/sda2
...
That's just a suggestion, really.
And what about character devices?
Perhaps Greg will chime in.
