From 8dca0a9a386a7e435889e7d621e5029a15dad612 Mon Sep 17 00:00:00 2001 From: Richard Yao <ryao@cs.stonybrook.edu> Date: Sat, 9 Feb 2013 19:25:55 -0500 Subject: Make spa.c assertions catch unsupported pre-feature flag pool versions A couple of assertions in spa.c were designed to prevent the use of invalid pool versions. They were written under the assumption that all valid pools are less than SPA_VERSION. Since feature flags jumped from 28 to 5000, any numbers in the range 28 to 5000 non-inclusive will fail to trigger them. We switch to the new SPA_VERSION_IS_SUPPORTED macro to correct this.
