autofs-5.1.9 - fix get parent multi-mount check in try_remount() From: Ian Kent In commit 635b90ecc (autofs-5.1.8 - fix mount tree startup reconnect) when getting the parent the check for a multi-mount should include a check for the root of the multi-mount as well since the root does not set its parent (it remains NULL). We could set the root parent to itself but that may have side effects because the convention has always been the parent is NULL for the multi-mount root.
