This is needed to allow memory tools like KASAN and KMSAN see the memory accesses from the checksum code. Without CONFIG_GENERIC_CSUM the tools can't see memory accesses originating from handwritten assembly code. For KASAN it's a question of detecting more bugs, for KMSAN using the C implementation also helps avoid false positives originating from seemingly uninitialized checksum values. Signed-off-by: Alexander Potapenko <glider@google.com> --- v2: - dropped the "default n" (as requested by Randy Dunlap) v4: - changed "net:" to "x86:" in the patch name Link: https://linux-review.googlesource.com/id/I3e95247be55b1112af59dbba07e8cbf34e50a581
