From d7cdc5febf9f2664755002c3a2f84bd348389fe9 Mon Sep 17 00:00:00 2001 From: Michael Halcrow Date: Tue, 16 Oct 2007 01:28:10 -0700 Subject: eCryptfs: update metadata read/write functions Update the metadata read/write functions and grow_file() to use the read_write.c routines. Do not open another lower file; use the persistent lower file instead. Provide a separate function for crypto.c::ecryptfs_read_xattr_region() to get to the lower xattr without having to go through the eCryptfs getxattr.
