This series of three patches adds SRP_CRED_REQ ans SRP_AER_REQ support in ib_srp. Both are information units defined in the SRP (draft) standard.
Changes in v5 compared to v4: - Added support for processing the SRP_AER_REQ information unit. - Introduced a new symbolic name, SRP_NORMAL_REQ_SQ_SIZE, that represents the maximum number of requests that may be queued by the SCSI mid-layer. - Changed transmit ring overflow check back to that of v3 (removed "- rsv" again). - Reduced the size of the srp_target_port.req_ring array by one element such that its size again matches the maximum number of requests that can be queued by the SCSI mid-layer. - Moved BUILD_BUG_ON_NOT_POWER_OF_2() statements to the module initialization function. - Updated patch descriptions. Changes in v4 compared to v3: - Dropped the fourth patch since it has been merged. - Introduced the symbolic constant SRP_TSK_MGMT_RSV, which represents the number of slots reserved in the tx ring for SRP task management requests. - One slot of the transmit ring buffer is now reserved for sending SRP_TSK_MGMT requests. - The BUILD_BUG_ON_NOT_POWER_OF_2() macro is now used to verify whether SRP_RQ_MASK and SRP_SQ_MASK really are bitmasks. - Rearranged function order such that no new forward declarations have to be introduced in the second patch. - Eliminated the srp_target_port.tx_req and tx_rsp variables. - Removed the SRP_OP_RSP flag. - Added a source code comment that explains why can_queue must be less than req_lim. Changes in v3 compared to v2: - Corrected completion queue size from SRP_REQ_SQ_SIZE (63) into SRP_SQ_SIZE (64). - Merged the two functions __srp_get_tx_req_iu() and __srp_get_tx_rsp_iu() into a single function __srp_get_tx_iu(). - Removed __attribute__((packed)) from the structure definitions added in include/scsi/srp.h because it was superfluous. - Modified descriptions of patches 1/4, 2/4 and 3/4. Changes in v2 compared to v1: - Split the big patch into multiple patches, which makes reviewing easier. - Instead of defining separate queues for transmitting requests and responses, a single queue is now used. -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
