eCryptfs: Copy lower directory inode times and size on link
The timestamps and size of a lower inode involved in a link() call was being copied to the upper parent inode. Instead, we should be copying lower parent inode's timestamps and size to the upper parent inode. I discovered this bug using the POSIX test suite at Tuxera.
