[Ocfs2-test-devel] [PATCH 0/11] Ocfs2-test: Add reflink tests for ocfs2 V3.

[tristan.ye]

Changes from v2 to v3:

- Add verification codes during stress testing to simulate OracleVM
operation on snapshotting.

- Fix some potential bugs in stress tests which may cause testcase run
into deadloop.

- Add a simple testcase  to reflink a list of files in a loop per joel's
request.

- Move reflink()(ioctl based) call to api-compat to make it compatible
for old kernels which have no reflink(2) implementation(it will be
included in mainline soon?)

- Trivial adjustments on testing workloads.

The v3 testing tools were against tao's v3 refcount kernel patches:-).

Regards,
Tristan.
