From 44842f647346cac4063b2bb8e9476fad09e363e7 Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Sat, 22 Jul 2023 10:28:37 -0600 Subject: iomap: use an unsigned type for IOMAP_DIO_* defines IOMAP_DIO_DIRTY shifts by 31 bits, which makes UBSAN unhappy. Clean up all the defines by making the shifted value an unsigned value. Reviewed-by: Darrick J. Wong Reported-by: Darrick J.
