From aa952eb26d4344fdad44c104f3c298d3130c53da Mon Sep 17 00:00:00 2001 From: Ian Kent Date: Tue, 15 Dec 2009 16:45:45 -0800 Subject: autofs4: use autofs_info for pending flag Eliminate the use of the d_lock spin lock by using the autofs super block info spin lock. This reduces the number of spin locks we use by one and makes the code for the following patch (to redirect ->d_revalidate() to ->lookup()) a little simpler.
