Subject: [PATCH RFC 2/2] xfstests: common/rc: add cluster size support for ext4
Date:   Fri, 24 Apr 2020 17:33:50 +0800
Message-Id: <1587720830-11955-3-git-send-email-jefflexu@linux.alibaba.com>
In-Reply-To: <1587720830-11955-1-git-send-email-jefflexu@linux.alibaba.com>
References: <1587720830-11955-1-git-send-email-jefflexu@linux.alibaba.com>
Sender: linux-ext4-owner@vger.kernel.org
Precedence: bulk

Inserting and collapsing range on ext4 with 'bigalloc' feature will
fail due to the offset and size should be alligned with the cluster
size.

The previous patch has add support for cluster size in fsx. Detect and
pass the cluster size parameter to fsx if the underlying filesystem
is ext4 with bigalloc.
