+# This test is a modified version of agskip test written by Alain Renaud.
+#
+# Phase 1: Create an xfs filesystem with AGCOUNT=32 and verify that the
+# AGCOUNT is 32.
+# Phase 2: Mount the filesystem with AGSKIP=3.
+# Phase 3: Verify that the AGSKIP is working correctly:
+# Create a file that spans more than one AG (size=1.5 * AGSIZE)
+# Create another file that is less than AGSIZE.
+# Use xfs_bmap to verify that the second extent is at location
+# previous_AG+1.
+# Continue creating/verifying that the AG's are created 3 AG's
+# apart
