namei.h query

[Saifi Khan]

Hi all:

Here is a newbie query regarding the code in namei.h

In DragonflyBSD, sys/sys/namei.h

struct componentname
{
 ...
 ...
 long cn_consume; /* chars to consume in lookup */
 ...
};

and

in FreeBSD RELENG_4, sys/sys/namei.h

struct componentname
{
 ...
 ...
 char *cn_pnbuf; /* pathname buffer */
 ...
 ...
};


What is the advantage of the DragonflyBSD approach in this case ?


thanks
Saifi.
