Subject: [PATCH v2 2/3] btrfs: fix argument type of btrfs_bio_clone_partial()
Date: Wed, 21 Jul 2021 15:26:59 +0900 [thread overview]
Message-ID: <c69cf6f0b81a28dd04b62537e3b8b4f46bd36e1e.1626848677.git.naohiro.aota@wdc.com> (raw)
In-Reply-To: <cover.1626848677.git.naohiro.aota@wdc.com>
From: Chaitanya Kulkarni <chaitanya.kulkarni@wdc.com>
The offset and can never be negative use unsigned int instead of int type
for them.
