[PATCH 0/1][Lucid][SRU] eCryptfs: Copy up lower inode attrs after setting lower xattr

From: Colin Ian King <colin.king at canonical.com>
After passing through a ->setxattr() call, eCryptfs needs to copy the
inode attributes from the lower inode to the eCryptfs inode, as they
may have changed in the lower filesystem's ->setxattr() path.
One example is if an extended attribute containing a POSIX Access
Control List is being set. The new ACL may cause the lower filesystem to
modify the mode of the lower inode and the eCryptfs inode would need to
be updated to reflect the new mode.
Backport of upstream commit 545d680938be1e86a6c5250701ce9abaf360c495
I delayed submitting this as I was trying to figure out why I
was getting false positives on the tests on Lucid and eventually
resolved the testing issue with acl mount options on ext4.
