From 3c3199852905ceb90a70e98777e71d369a5f0823 Mon Sep 17 00:00:00 2001 From: Ian Kent Date: Fri, 25 Mar 2011 01:51:08 +0800 Subject: autofs4 - reinstate last used update on access When direct (and offset) mounts were introduced the the last used timeout could no longer be updated in ->d_revalidate(). This is because covered direct mounts would be followed over without calling the autofs file system. As a result the definition of the busyness check for all entries was changed to be "actually busy" being an open file or working directory within the automount. But now we have a call back in the follow so the last used update on any access can be re-instated. This requires DCACHE_MANAGE_TRANSIT to always be set.
