Subject: osdc: Add split_op statistic
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=b973092c57c3ab192b18f577d6e9e9d5a69da4ec;p=ceph-ci.git

osdc: Add split_op statistic

This statistic counts the number of OPs which have been submitted using the
split op mechanism.  It allows a user to check how useful this is and
performance/development to check that this mechanism is being used in
any given application.
