Here you do a mempool allocation to guarantee forward progress.. > + request->sge = kzalloc(sizeof(struct ib_sge), GFP_KERNEL); > + if (!request->sge) > + goto allocate_sge_failed; ... and here it's a plain malloc in the same path, which renders the above useless. Also I would just embedd the sge into the containing structure to avoid a memory allocation. > + request->info = info; > + > + packet = (struct smbd_negotiate_req *) request->packet; > + packet->min_version = cpu_to_le16(0x100); > + packet->max_version = cpu_to_le16(0x100); Canyou add a constant for the version code? > + packet->reserved = cpu_to_le16(0); no need to byte swap 0 - you can always assign it directly.
