Subject: qemu: Move and rename qemuDomainCheckEjectableMedia to qemuProcessRefreshDisks
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=d9bee413ade28e1e43ef222c7aaaa3c6d6fda0f1;p=libvirt.git

qemu: Move and rename qemuDomainCheckEjectableMedia to qemuProcessRefreshDisks

Move it to a more sane place since it's refreshing data about disks.
