Hi !

I'm using devfs on a small 2.6.0t7 kernel and I have software which relies on the exactitude of /proc/partitions.
The problem is that in /proc/partition I have something like

  3     0   19925880 hda
  3     1   19920568 hda1

where a 2.4.x kernel gave me:

  3     0   19925880 ide/host0/bus0/target0/lun0/disc
  3     1   19920568 ide/host0/bus0/target0/lun0/part1

I've enabled the following options:

CONFIG_DEVFS_FS=y
CONFIG_DEVFS_MOUNT=y

Any idea, why this has changed ?

Cheers,

Yes, the 2.4 devfs behaviour was buggy - it was different from the non-devfs output. Note that you can't rely on the names in /proc/partitions anyway as the system administrator is free to name the block devices however he wants.
