Subject: ceph-disk:  udevadm settle before partprobe
X-Git-Tag: v0.62~175
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=9eda8e5d5abf0743a2ad484806cfb2018243515f;p=ceph.git

ceph-disk:  udevadm settle before partprobe

After changing the partition table, allow the udev event to be
processed before calling partprobe.  This helps prevent partprobe
from getting a resource busy error on some platforms.
