Callers of rxe_mem_copy() provide pointer to store updated CRC value. That pointer was supposed to be updated, but the commitcee2688e3c("IB/rxe: Offload CRC calculation when possible") mistakenly removed that assignment for RXE_MEM_TYPE_DMA memory type. The code worked because there are no actual callers with RXE_MEM_TYPE_DMA, who are interested in returned value of crcp. The one caller in read_reply(), who uses the returned crcp didn't set RXE_MEM_TYPE_DMA as mem->type.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
