The first three patches fix real bugs - the first two fix bugs in ext3 leading to false reports of EIO errors from JBD and aborted journal, the third patch fixes a bug in block_write_full_page() which can possibly lead to data corruption. With these patches, don't see the data corruption I was able to reproduce with fsx-linux under UML. I'm not yet sure whether all the problems HP reported are gone (they're testing now) but since this seems to be a nasty problem I'm posting earlier rather than later. Please someone have a look whether my fix and analysis looks sane. Thanks.
