Subject: [PATCH 2/2] ext4/005: Add new resize2fs stress test
Date: Tue, 9 Dec 2014 23:27:27 +0400 [thread overview]
Message-ID: <1418153247-17435-2-git-send-email-dmonakhov@openvz.org> (raw)
In-Reply-To: <1418153247-17435-1-git-send-email-dmonakhov@openvz.org>
Run several rounds of resize2fs. Increment fs-size on random amount bytes on each
iteration while fsstress is in progress.
