Dear all.
I'm trying to make some modifications to SCSI driver to correctly sync
/proc/partitions when new disk is inserted.
To revalidate disk I used sd_revalidate_disk(), but this function revalidate
only disk info, but do not rescan partition table. How can I tell the driver
to correctly rescan part/ table? I've tried to use rescan_partitions()
function like below, but failed:
struct scsi_disk *sdkp;
bdev = bdget_disk(sdkp->disk, 0);
rescan_partitions(sdkp->disk, bdev);
But in this case bdev->bd_disk is NULL. Why? What did I do not correct?
Thank for help.

Can be done from userland: blockdev --rereadpt /dev/whatever .
