+ * FS Summary Counters
+ * ===================
+ *
+ * The basics of filesystem summary counter checking are that we iterate the
+ * AGs counting the number of free blocks, free space btree blocks, per-AG
+ * reservations, inodes, delayed allocation reservations, and free inodes.
+ * Then we compare what we computed against the in-core counters.
+ *
+ * However, the reality is that summary counters are a tricky beast to check.
+ * While we /could/ freeze the filesystem and scramble around the AGs counting
+ * the free blocks, in practice we prefer not do that for a scan because
+ * freezing is costly.  To get around this, we added a per-cpu counter of the
+ * delalloc reservations so that we can rotor around the AGs relatively
+ * quickly, and we allow the counts to be slightly off because we're not taking
+ * any locks while we do this.
+ *
+ * So the first thing we do is warm up the buffer cache in the setup routine by
+ * walking all the AGs to make sure the incore per-AG structure has been
+ * initialized.  The expected value calculation then iterates the incore per-AG
+ * structures as quickly as it can.  We snapshot the percpu counters before and
+ * after this operation and use the difference in counter values to guess at
+ * our tolerance for mismatch between expected and actual counter values.
+ */
+
+/*
+ * Since the expected value computation is lockless but only browses incore
+ * values, the percpu counters should be fairly close to each other.  However,
+ * we'll allow ourselves to be off by at least this (arbitrary) amount.
+ */
