[Ocfs2-test-devel] [PATCH 0/12] Ocfs2-test: Add reflink tests for ocfs2 V5.

[Tristan]

Reflink test on linus's MM kernel branch is performing in progress, till 
now, all single-node testcases has passed during such tests, while 
multi-nodes tests failed at bug 1185 
http://oss.oracle.com/bugzilla/show_bug.cgi?id=1185

However, the testing tools itself was getting more and more matured, I'd 
like to post v5 version since it was running stably on recent MM kernel.

Changes from v4 to v5:

- Add testcase for O_DIRECT case

- Add testcase for 'date=writeback' mounting option

- Add testcase for 'inline-data' case

- Fix a return code error.

- Other minor enhancements for both single-node and multi-nodes launchers.


Regards,
Tristan.
