From: Keith Busch <kbu...@kernel.org> The 6.0 kernel made some changes to the direct io interface to allow offsets in user addresses. This based on the hardware's capabilities reported in the request_queue's dma_alignment attribute.
dm-crypt, -log-writes and -integrity require direct io be aligned to the block size. Since it was only ever using the default 511 dma mask, this requirement may fail if formatted to something larger, like 4k, which will result in unexpected behavior with direct-io. Changes since v1: Added the same fix for -integrity and -log-writes The first three were reported successfully tested by Dmitrii Tcvetkov, but I don't have an official Tested-by: tag. https://lore.kernel.org/linux-block/20221103194140.06ce3...@xps.demsh.org/T/#mba1d0b13374541cdad3b669ec4257a11301d1860 Keitio errors on Busch (5): block: make dma_alignment a stacking queue_limit dm-crypt: provide dma_alignment limit in io_hints block: make blk_set_default_limits() private dm-integrity: set dma_alignment limit in io_hints dm-log-writes: set dma_alignment limit in io_hints block/blk-core.c | 1 - block/blk-settings.c | 9 +++++---- block/blk.h | 1 + drivers/md/dm-crypt.c | 1 + drivers/md/dm-integrity.c | 1 + drivers/md/dm-log-writes.c | 1 + include/linux/blkdev.h | 16 ++++++++-------- 7 files changed, 17 insertions(+), 13 deletions(-) -- 2.30.2 -- dm-devel mailing list dm-devel@redhat.com https://listman.redhat.com/mailman/listinfo/dm-devel
