One-element arrays are deprecated, and we are replacing them with flexible array members instead. So, replace one-element array with flexible-array member in struct hpt_iop_request_scsi_command and refactor the rest of the code, accordingly. The following pieces of code suggest that the one element of array sg_list in struct hpt_iop_request_scsi_command is not taken into account when calculating the total size for both struct hpt_iop_request_scsi_command and the maximum number of elements sg_list will contain: 1047 req->header.size = cpu_to_le32( 1048 sizeof(struct hpt_iop_request_scsi_command) 1049 - sizeof(struct hpt_iopsg) 1050 + sg_count * sizeof(struct hpt_iopsg)); 1400 req_size = sizeof(struct hpt_iop_request_scsi_command) 1401 + sizeof(struct hpt_iopsg) * (hba->max_sg_descriptors - 1); So it's safe to replace the one-element array with a flexible-array member and update the code above, accordingly: now we don't need to subtract sizeof(struct hpt_iopsg) from sizeof(struct hpt_iop_request_scsi_command) because this is implicitly done by the flex-array transformation.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
