Hi Al,

you "unofficially" told me that you want to get rid of '->write_super()'
and 'sync_supers()' should not exist. And FSes which really need
'->write_super()' should implement that themselves.

I will try to work on this, but a bit later, after my holidays. But
could you please:

1. confirm that you want to kill '->write_super()' and '->s_dirt'
   "officially", so that I could refer to this when sending patches

2. pick up patches 1-6 from this series, this would make my life easier
   a bit.

I'm not sure then what do do with:

commit 140236b4b1c749c9b795ea3d11558a0eb5a3a080
Author: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

    VFS: introduce s_dirty accessors

which Linus merged, but which is now not needed, since you now want me
to kill '->write_super()' completely. Will you take care of this please?

Thanks!
