[PATCH] reiserfs mark_journal_new

[Chris Mason <mason@suse.com>]

Hi guys,

The 2.2.x reiserfs journal code marks newly allocated metadata so that if
it is freed in the same transaction (common due to balancing), it can
immediately be reused as a data block.  It also allows faster freeing for
these blocks.

This tested patch enables that code for 2.4.x, Alan please include.
