[PATCH 0/4] Fix bugs and possible data corruption if blocksize < pagesize

[Jan Kara]

  Hi,

  lately, I've been tracking some problems with ext3 reported by HP on ia64 and
this is what I came with. 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.
