eCryptfs: Copy up lower inode attrs in getattr
commit 55f9cf6bbaa682958a7dd2755f883b768270c3ce upstream. The lower filesystem may do some type of inode revalidation during a getattr call. eCryptfs should take advantage of that by copying the lower inode attributes to the eCryptfs inode after a call to vfs_getattr() on the lower inode. I originally wrote this fix while working on eCryptfs on nfsv3 support, but discovered it also fixed an eCryptfs on ext4 nanosecond timestamp bug that was reported. https://bugs.launchpad.net/bugs/613873 Signed-off-by: Tyler Hicks <tyhicks@linux.vnet.ibm.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
