Hi all,
Currently when calling commit() on a ped_disk, the following happens:
open /dev/sda
write partition table
close /dev/sda
open /dev/sda
ioctl (BLKRRPART)
close /dev/sda
This is rather inefficient, and causes 2 udev change events to be fired
for /dev/sda (+ the change events from the BLKRRPART), causing all kind
of scanning (blkid & friends) twice.
The attached patch fixes things to only open the device once.
Regards,
Hans
