Subject: blockd: don't flush devices list on "hotplug" call
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=12851d6b3a3883b8470ba3f8c18024dec51e2847;p=project%2Ffstools.git

blockd: don't flush devices list on "hotplug" call

The point of "hotplug" call is to add or remove a single entry to/from
devices list. Using vlist_update() and vlist_flush() was clearing whole
list (and leaving the last entry in case of adding a device).
