These patches can be applied on top of Sagi's "[v1] Simlify dif_verify routines and fixup fileio protection information code" patchset. * Changes from v2: - Introduces crc_t10dif_update() to calculate CRC by mutiple calls - Handle odd SG mapping correctly instead of giving up * Changes from v1: - Reduce code duplication a bit in target_read_prot_action() - Fix sbc_dif_verify() for WRITE_SAME command - Fix inverted rw argument for fd_do_rw() - Perform DIF verify before write for WRITE_SAME Akinobu Mita (5): target: ensure se_cmd->t_prot_sg is allocated when required lib: introduce crc_t10dif_update() target: handle odd SG mapping for data transfer memory target: Fix sbc_dif_generate() and sbc_dif_verify() for WRITE SAME target/file: enable WRITE SAME when protection info is enabled drivers/target/target_core_file.c | 18 +++-- drivers/target/target_core_sbc.c | 136 +++++++++++++++++++++++---------- drivers/target/target_core_transport.c | 30 +++++--- include/linux/crc-t10dif.h | 1 + include/target/target_core_base.h | 1 + lib/crc-t10dif.c | 23 ++++++ 6 files changed, 153 insertions(+), 56 deletions(-) Cc: Tim Chen <tim.c.chen@xxxxxxxxxxxxxxx> Cc: Herbert Xu <herbert@xxxxxxxxxxxxxxxxxxx> Cc: "David S.
