Subject: [PATCH blktests v2 3/9] common-xfs: Make size argument optional for _xfs_run_fio_verify_io
Date:   Thu, 20 Apr 2023 20:31:13 +0200
Message-Id: <20230420183121.4489-5-dwagner@suse.de>
In-Reply-To: <20230420183121.4489-1-dwagner@suse.de>
References: <20230420183121.4489-1-dwagner@suse.de>

Precedence: bulk

Make the size argument optional by reading the filesystem info. The
caller doesn't have to guess (or calculate) how big the max IO size.
The log data structure of XFS is reducing the capacity.
