Hi.
I'd like to add two non-standard value to the sysconf(3) functions,
which can be found in both Solaris and Linux: _SC_PHYS_PAGES and
_SC_AVPHYS_PAGES.
The patch is here:
http://people.freebsd.org/~pjd/patches/sysconf.patch
Can someone review it? Thanks.
What are they for? My concern is that _SC_AVPHYS_PAGES isn't going to
semantically match other platforms since in a steady state the free count
is small on FreeBSD, but on other systems it swings quite a bit based on
load.
_SC_PHYS_PAGES is used by libzpool (a part of the ZFS file system).
_SC_AVPHYS_PAGES I used more for completness.
OK. I'd be somewhat inclined to leave _SC_AVPHYS_PAGES out in that
case, but I don't feel strongly about it.
I've no opinion, I can remove it.
What's the status of _SC_PHYS_PAGES? I'm porting mbuffer [1], which
uses _SC_PHYS_PAGES.
I just committed it to HEAD.
