Description of problem:
If the donor file is an append-only file, we should not allow the operation to proceed, lest we end up overwriting the contents of an append-only file.
Red Hat would like to thank Dan Rosenberg for reporting this issue.
This issue did not affect the version of Linux kernel as shipped with Red Hat
Enterprise Linux 3, 4 and Red Hat Enterprise MRG as they did not include support for the Ext4 filesystem. A future kernel update in Red Hat Enterprise Linux 5 will address this issue.
