From: Dmitry Monakhov Date: Wed, 20 Feb 2013 10:42:13 +0000 (+0000) Subject: xfstest: add fallocate/punch_hole vs AIO/DIO stress test X-Git-Tag: v2022.05.01~3534 X-Git-Url: http://git.apps.os.sepia.ceph.com/?a=commitdiff_plain;h=892125a53aac8e82dec99fe4e824c39513d4a17a;p=xfstests-dev.git xfstest: add fallocate/punch_hole vs AIO/DIO stress test Run random AIO/DIO activity (fio's job:direct_aio_raicer) random fallocate activity(fio's job:falloc_raicer) and random punch_hole activity(punch_hole_raicer) on a common file in parallel. If a race exists, old dio request may rewrite punched block after it was allocated to another file, we will catch that by verifier fio's job: "aio-dio-verifier".
