Subject: eCryptfs: Copy up lower inode attrs in getattr
From: Tyler Hicks <tyhi...@linux.vnet.ibm.com>
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.
