Hi Glenn -

I'm afraid it's not as simple as a series of commands. I do need to
update the patch to the 2.6.29 version which doesn't have the
- ->commit_write and ->prepare_write hooks that have been removed. The
other thing is that it needs more support in the kernel itself.
Previously it was limited to exports and adding a new hook, which I
could accept without much worry. I'm concerned about whether
set_buffers_dirty_notag() will make it upstream and I'm uncertain of the
interactions.

Edward - What's the reasoning behind it? Has it been submitted upstream
yet? Is it possible to use reiser4_set_dirty_pages creatively to get
the same effect?
