overflow: Allow non-type arg to type_max() and type_min()
[ Upstream commit bd1ebf2 ] A common use of type_max() is to find the max for the type of a variable. Using the pattern type_max(typeof(var)) is needlessly verbose. Instead, since typeof(type) == type we can just explicitly call typeof() on the argument to type_max() and type_min(). Add wrappers for readability. We can do some replacements right away: $ git grep '\btype_\(min\|max\)(typeof' | wc -l 11 Link: https://lore.kernel.org/r/20240301062221.work.840-kees@kernel.org Signed-off-by: Kees Cook <keescook@chromium.org> Signed-off-by: Sasha Levin <sashal@kernel.org>
