+# FS QA Test No. generic/043
+#
+# Test multiple fallocate insert/collapse range calls on same file.
+# For different blocksizes, Call insert range a single alternate block
+# multiple times until the file is left with 100 extents and as much
+# number of extents. And Call collapse range about the previously inserted
+# ranges to test merge code of collapse range.
+# Also check for file system consistency after completing this operation
+# for each blocksize.
