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.
