IB/core: Remove ib_sg_dma_address() and ib_sg_dma_len()

2019-02-04T21:34:07Z

Keeping single line wrapper functions is not useful. Hence remove the ib_sg_dma_address() and ib_sg_dma_len() functions. This patch does not change any functionality. Signed-off-by: Bart Van Assche Signed-off-by: Jason Gunthorpe

IB/iser: Pass the correct number of entries for dma mapped SGL

2019-01-18T21:12:24Z

ib_dma_map_sg() augments the SGL into a 'dma mapped SGL'. This process may change the number of entries and the lengths of each entry. Code that touches dma_address is iterating over the 'dma mapped SGL' and must use dma_nents which returned from ib_dma_map_sg(). ib_sg_to_pages() and ib_map_mr_sg() are using dma_address so they must use dma_nents.

IB/iser: Inline two work request conversion functions

2018-07-31T01:59:40Z

Since the next patch will change the return type of these functions into a const pointer and since the iSER driver modifies the work request these functions return a pointer two, inline two work request conversion function calls. This patch does not change any functionality. Signed-off-by: Bart Van Assche Reviewed-by: Sagi Grimberg Reviewed-by: Max Gurtovoy Signed-off-by: Jason Gunthorpe

block: move ref_tag calculation func to the block layer

2018-07-30T14:27:01Z

Currently this function is implemented in the scsi layer, but it's actual place should be the block layer since T10-PI is a general data integrity feature that is used in the nvme protocol as well.

IB: Correct MR length field to be 64-bit

2017-09-25T15:47:23Z

The ib_mr->length represents the length of the MR in bytes as per the IBTA spec 1.3 section 11.2.10.3 (REGISTER PHYSICAL MEMORY REGION). Currently ib_mr->length field is defined as only 32-bits field. This might result into truncation and failed WRs of consumers who registers more than 4GB bytes memory regions and whose WRs accessing such MRs. This patch makes the length 64-bit to avoid such truncation.
