eCryptfs: Regression in unencrypted filename symlinks
The addition of filename encryption caused a regression in unencrypted filename symlink support. ecryptfs_copy_filename() is used when dealing with unencrypted filenames and it reported that the new, copied filename was a character longer than it should have been. This caused the return value of readlink() to count the NULL byte of the symlink target. Most applications don't care about the extra NULL byte, but a version control system (bzr) helped in discovering the bug.
