X-Git-Tag: testing/wip-batrick-testing-20240411.154038~94^2
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=3afae90cd3ecdbf7489d1589e572460966e87c48;p=ceph-ci.git

ceph_test_rados_api_io_pp: add multiple extents test for sparse-read

Just test more with a larger size to test the sparse-read to find
some corner case bugs.
