Make sure we can actually upgrade filesystems to support inode btree
counters.

+# FS QA Test No. 764
+#
+# Functional testing for xfs_admin -O, which is a new switch that enables us to
+# add features to an existing filesystem.  In these test scenarios, we try to
+# add the inode btree counter 'feature' to the filesystem, and make sure that
+# NEEDSREPAIR (aka the thing that prevents us from mounting after an upgrade
+# fails) is clear if the upgraded succeeds and set if it fails.
+#
+# The first scenario tests that we can't add inobtcount to the V4 format,
+# which is now deprecated.
+#
+# The middle five scenarios ensure that xfs_admin -O works even when external
+# log devices and realtime volumes are specified.  This part is purely an
+# exerciser for the userspace tools; kernel support for those features is not
+# required.
+#
+# The last scenario uses a xfs_repair debug knob to simulate failure during an
+# inobtcount upgrade, then checks that mounts fail when the flag is enabled,
+# that repair clears the flag, and mount works after repair.
