From: David Jeffery Date: Mon, 6 May 2013 05:49:30 +0000 (+0800) Subject: autofs - remove autofs dentry mount check X-Git-Tag: v3.2.46~82 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9670f6d8280fa5be96c38e7f8415c70eafd511c7;p=pandora-kernel.git autofs - remove autofs dentry mount check commit ce8a5dbdf9e709bdaf4618d7ef8cceb91e8adc69 upstream. 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.
