I just noticed that md devices do not show up in /proc/partitions in 2.6.
I realise that they don't actually have partitions and are just 'whole devices', but other whole devices do appear in /proc/partitions (Along with their partitions if any).
This seems to be a regression from 2.4 where md devices do appear in /proc/partitions.
The cause appears to be a patch from 'torvalds' some 15 months ago (in version 1.36 for drivers/block/genhd.c) which has the comment:
Avoid confusion "mount" and "fsck" - don't show things like floppies and CD's in /proc/partitions.
It excluded devices that cannot be partitioned, and devices with zero size from /proc/partitions.
The 'zero size' possibly makes sense (2.4 excludes those), but I would like to register a vote against excluding devices without partitions, as this excluded 'md' devices and I would really like them to be included.
Is there really a good reason for this? How badly does mount get confused? and is that not the fault of mount?
