From 82b16528405131eadc18285da982d4806f6db34e Mon Sep 17 00:00:00 2001 From: Dmitriy Monakhov Date: Mon, 5 Mar 2007 00:30:46 -0800 Subject: [PATCH] [PATCH] ecryptfs: lower root result must be adirectory - Currently after path_lookup succeed we dot't have any guarantie what it is DIR. This must be explicitly demanded. - path_lookup can't return negative dentry, So inode check is useless.
