e9f5f44a - block: remove the blk_integrity_profile structure

Thu, 13 Jun 2024 08:48:15 +0000

block: remove the blk_integrity_profile structureBlock layer integrity configuration is a bit complex right now, as itindirects through operation vectors for a simple two-dimensionalconfiguration: a) the checksum type of none, ip checksum, crc, crc64 b) the presence or absence of a reference tagRemove the integrity profile, and instead add a separate csum_type flagwhich replaces the existing ip-checksum field and a new flag thatindicates the presence of the reference tag.This removes up to two layers of indirect calls, remove the need tooffload the no-op verification of non-PI metadata to a workqueue andgenerally simplifies the code. The downside is that block/t10-pi.c nowhas to be built into the kernel when CONFIG_BLK_DEV_INTEGRITY issupported. Given that both nvme and SCSI require t10-pi.ko, it is loadedfor all usual configurations that enabled CONFIG_BLK_DEV_INTEGRITYalready, though.Signed-off-by: Christoph Hellwig Reviewed-by: Kanchan Joshi Reviewed-by: Hannes Reinecke Reviewed-by: Martin K.
