From 868eb7a8539d3e8c494209be2b1f4084a274dfef Mon Sep 17 00:00:00 2001 From: Jan Blunck Date: Thu, 1 May 2008 04:35:10 -0700 Subject: autofs: path_{get,put}() cleanups Here are some more places where path_{get,put}() can be used instead of dput()/mntput() pair. Besides that it fixes a bug in autofs4_mount_busy() where mntput() was called before dput().
