# Test steps:
# The test checks to make sure that the trusted.pgfid.xx xattr is set on
# both the linkto and data files post the final rename.
# The test creates files file-1 and file-3 so that src_hashed = dst_hashed,
# src_cached = dst_cached and xxx_hashed != xxx_cached.
# It then renames file-1 to file-3 which triggers the posix_mknod call
# which updates the trusted.pgfid.xx xattr.
