Modified files:
sys/compat/opensolaris/kern opensolaris_kmem.c
sys/compat/opensolaris/sys kmem.h
Log:
Change type of kmem_used() and kmem_size() functions to uint64_t, so it
doesn't overflow in arc.c in this check:
if (kmem_used() > (kmem_size() * 4) / 5)
return (1);
With this bug ZFS almost doesn't cache.
Only 32bit machines are affected that have vm.kmem_size set to values >=1GB.
