Reiser4, 2.6.28-rc2-mm1 and prepare_write / commit_write

It looks like 2.6.28 committed the removal of prepare_write and
commit_write.  They are apparently replaced with write_begin and write_end.

I thought about trying to convert Reiser4 myself but it was already past
midnight and it looked like it might be six hour job.

The conversion does not look too complicated, but there may be some
tricky issues.

I am wondering if you are already working on this, Edward?

Yup.

This is only for loop devices, so if you don't use it,
you can get rid of reiser4_{prepare,commit}_write
and supply NULL to vfs as a temporary fixup.

Thanks,
Edward.
