buffer to mark 
.SH "DESCRIPTION"
.PP
mark dirty metadata which needs to be journaled as part of the current
transaction.
.PP
The buffer is placed on the transaction's metadata list and is marked
as belonging to the transaction.  
.PP
Returns error number or 0 on success.  
.PP
Special care needs to be taken if the buffer already belongs to the
current committing transaction (in which case we should have frozen
data present for that commit).  In that case, we don't relink the
.SH "BUFFER"
.PP
that only gets done when the old transaction finally
completes its commit.
