Use ecryptfs_dentry_to_lower_path in a couple of places
There are two places in ecryptfs that benefit from using ecryptfs_dentry_to_lower_path() instead of separate calls to ecryptfs_dentry_to_lower() and ecryptfs_dentry_to_lower_mnt(). Both sites use fewer instructions and less stack (determined by examining objdump output). Signed-off-by: Matthew Wilcox <willy@linux.intel.com> Signed-off-by: Tyler Hicks <tyhicks@canonical.com>
