srp_map_data(9)

🌸 NAME 🌸

okay so bestie, this is srp_map_data(9) from the Kernel API Manual, and it's literally the function that maps a SCSI data buffer onto an SRP request. no cap. ✨

✨ SYNOPSIS ✨

       int srp_map_data (struct scsi_cmnd *scmnd , struct srp_rdma_ch *ch ,
       struct srp_request *req );

🎀 ARGUMENTS 🎀

• scmnd — the SCSI command to map. this is the thing getting mapped, main character behavior 💅
• ch — the SRP RDMA channel. think of it as the lane this request is rolling through 🦋
• req — the SRP request. yes bestie, the request itself 🎀

💖 DESCRIPTION 💖

It returns the length in bytes of the SRP_CMD IU, or a negative value if the mapping failed 😭. and important: the size of any immediate data is not included in the return value — not even a little, periodt 🙈.

🦋 SEE ALSO 🦋
