autofs-5.1.9 - fix get parent multi-mount check in try_remount()
|
|
|
|
From: Ian Kent <raven@themaw.net>
|
|
|
|
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.
