Adding/deleting partitions does not notify DevFS

["Hong H. Pham" <hhp@xxxxxxxxxxx>]

Hi,

The functions add_partition() and del_partition(), for the ioctl()
commands BLKPG_ADD_PARTITION and BLKPG_DEL_PARTITION respectively, in
drivers/block/blkpg.c do not notify the devfs system that the
partition layout has been changed.  Consequently, the desired symlinks
in /dev/discs/... disappear and the entries in /proc/partitions are
invalid.

I am using the 2.4.16 kernel.  This problem can be verified by using GNU
libparted (1.5.x) on a system running DevFS.  Use the command 'parted' to
add or delete a partition (but at least one partition should exist), and
commit to disk.

Cheers,
..Hong
