Although not reproduced in practice, these two cases may be
considered by UBSAN as off-by-one errors. So fix them in the

If the offsetof() of a given flexible array member (fam) is smaller
than the sizeof() of the containing struct, then the struct_size()
macro reports a size which is too big.
This occurs when the two conditions below are met:

Recently I'm trying to compile my (almost) x86_64_defconfig based kernel with
`make W=1` while having CONFIG_WERROR=y. With a handful of patches I was able
to achieve that with clang-18, however GCC 14.2.0 issues a lot of additional
warnings that are mostly related to -Wformat-truncation [1]. Any s

Add the __counted_by compiler attribute to the flexible array member
attrs to improve access bounds-checking via CONFIG_UBSAN_BOUNDS and
CONFIG_FORTIFY_SOURCE.
Increment num before adding a new param_attribute to the attrs array and
adjust the array index accordingly. Increment num immediately aft

than the sizeof() of the containing struct, then the struct_size()
macro reports a size which is too big.
