From ce8a5dbdf9e709bdaf4618d7ef8cceb91e8adc69 Mon Sep 17 00:00:00 2001 From: David Jeffery Date: Mon, 6 May 2013 13:49:30 +0800 Subject: [PATCH] autofs - remove autofs dentry mount check When checking if an autofs mount point is busy it isn't sufficient to only check if it's a mount point. For example, if the mount of an offset mountpoint in a tree is denied for this host by its export and the dentry becomes a process working directory the check incorrectly returns the mount as not in use at expire. This can happen since the default when mounting within a tree is nostrict, which means ingnore mount fails on mounts within the tree and continue. The nostrict option is meant to allow mounting in this case.
