From c7eb26678e59f16f4e84f1176d187cd21a27414d Mon Sep 17 00:00:00 2001 From: Dave Hansen Date: Tue, 16 Oct 2007 23:31:14 -0700 Subject: [PATCH] r/o bind mounts: give permission() a local 'mnt' variable First of all, this makes the structure jumping look a little bit cleaner. So, this stands alone as a tiny cleanup. But, we also need 'mnt' by itself a few more times later in this series, so this isn't _just_ a cleanup.
