Subject: [PATCH v9 9/11] xfstests: generic/043: Test multiple fallocate insert/collapse range calls
Date: Thu, 22 Jan 2015 00:12:04 +0900	[thread overview]
Message-ID: <1421853126-4505-10-git-send-email-linkinjeon@gmail.com> (raw)

Changelog
v9:
 - check that mkfs and mount succeed.
 - check extent_before and extent_after instead of hardcode 1.
 - remove umount.

v8:
 - use MKFS_OPTION to use blocksize in configuration and remove loop.
 - remove trailing space.
 - compare original file and test file to check data integrity.

+# FS QA Test No. generic/043
+#
+# Test multiple fallocate insert/collapse range calls on same file.
+# 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 data integrity and file system consistency.
