The patch i propose is tiny, simple and straight forward. It
touches only one file and leaves the CSA code in a configurable
loadable module. It broke nobody's code and it does not need to
redesign existing BSD kernel code and utilities.
If we are to merge the code, there are some detailed discuss

I did not look into the userspace commands supported in BSD
accounting on the dependency on the format of /var/account/pacct
file.
The accounting exit hook allows BSD/CSA to save accounting
data stored in task_struct to internally kept data structure
and then writes to their respective accounting f

Sorry I was not clear on my point.
I was trying to point out that, an exit hook for BSD and CSA is
essential to save accounting data before the data is gone. That
can not be done with a netlink.
So, my patch was to keep acct_process as a wrapper, which
would then call do_exit_csa() for CSA and call

Since my idea of providing an accounting framework was considered
'overkill', here i submit a tiny patch just to allow CSA to
handle end-of-process (eop) situation by saving off accounting
data before a task_struct is disposed.
This patch is to modify the acct_process() in acct.c, which is
invoked
