Linus, et al,
Here are the major ocfs2 fixes for 2.6.35-rc5. A few more
fixes have trickled in, but as these major fixes have been tested, I
didn't want to delay them any longer.
The first major fix you know about: the tail zeroing fix when
extending files. It's been run under heavy testing for a week now, and
we're quite happy. We should also no longer be touching any pages past
i_size in write or CoW.
The second major fix was discovered and fixed by Mark and Jan.
The jbd2 triggers we added for block checksumming had a small window
where the checksum from transaction N-2 could be written in transaction
N-1 because transaction N accessed the buffer but never actually
modified it. We fix this by checksumming at the moment we freeze the
data rather than the moment we write the commit. This was a hard bug
to trap, and very good work by Mark and Jan.
Please pull.

Joel
