[PATCH 11/11] xfstests: Test multiple fallocate insert/collapse range calls

From: Namjae Jeon
Date: Thu Dec 18 2014 - 04:46:54 EST


This testcase(043) tries to test finsert range a single alternate block
mulitiple times and test merge code of collase range.

+# 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 1024 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.
