FreeBSD 10.1 Memory Exhaustion

[Christopher Forgeron]

I found the same thing - The older patch does apply on 10.1 with one line
needing to be added manually. Did that, but I'm running into this when I
try a make buildworld:

/usr/src/cddl/lib/libzpool/../../../sys/cddl/contrib/opensolaris/uts/common/fs/zfs/arc.c:2726:30:
error: use of undeclared identifier 'freemem'
        if (zfs_arc_cache_target && freemem < zfs_arc_cache_target +
btop(size)) {
                                    ^
/usr/src/cddl/lib/libzpool/../../../sys/cddl/contrib/opensolaris/uts/common/fs/zfs/arc.c:2726:63:

        if (zfs_arc_cache_target && freemem < zfs_arc_cache_target +
btop(size)) {
                                                                     ^

                kmem_cache_reap(cache, zfs_arc_cache_free_max);
                ^

        cachefree = kmem_cache_free_size(buf_cache) +

I see freemem defined in sys/cddl/compat/opensolaris/sys/kmem.h, and I've
done a make clean; make clean; make cleanworld; make depend before running
make buildworld.

What am I forgetting to make here?
