From: Arnd Bergmann The impliied padding causes a harmless warning when testing the uapi headers with -Wpadded that could in theory indicate incompatibilies or data leaks: ./usr/include/linux/alloc_tag.h:41:1: error: padding struct size to alignment boundary with 7 bytes [-Werror=padded] The code here is fine, but it's better to make the padding explicit and avoid the warning here.
