From 6510c9d8595adcee2b0dc86408bc432a8dd7d652 Mon Sep 17 00:00:00 2001 From: Ian Kent Date: Tue, 15 Dec 2009 16:45:47 -0800 Subject: [PATCH] autofs4: cleanup active and expire lookup The lookup functions for active and expiring dentrys use parameters that can be easily obtained on entry so we change the call to to take just the dentry. This makes the subsequent change, to send all lookups to ->lookup(), a bit cleaner.
