+Subject: lib: zstd: Refactor intentional wrap-around test
+
+In an effort to separate intentional arithmetic wrap-around from
+unexpected wrap-around, we need to refactor places that depend on this
+kind of math. One of the most common code patterns of this is:
+
+	VAR + value < VAR
+
+Notably, this is considered "undefined behavior" for signed and pointer
+types, which the kernel works around by using the -fno-strict-overflow
+option in the build[1] (which used to just be -fwrapv). Regardless, we
+want to get the kernel source to the position where we can meaningfully
+instrument arithmetic wrap-around conditions and catch them when they
+are unexpected, regardless of whether they are signed[2], unsigned[3],
+or pointer[4] types.
+
+Switch to a more regular type for a 64-bit value and refactor the
+open-coded wrap-around addition test to use subtraction from the type max
+(since add_would_overflow() may not be defined in early boot code). This
+paves the way to enabling the wrap-around sanitizers in the future.
