Subject: [PATCH 9/9] iomap: use an unsigned type for IOMAP_DIO_* defines
Date: Fri, 21 Jul 2023 10:16:50 -0600	[thread overview]
Message-ID: <20230721161650.319414-10-axboe@kernel.dk> (raw)
In-Reply-To: <20230721161650.319414-1-axboe@kernel.dk>

IOMAP_DIO_DIRTY shifts by 31 bits, which makes UBSAN unhappy. Clean up
all the defines by making the shifted value an unsigned value.
