ktime_compare_safe(9)

💅 ktime_compare_safe — from the Kernel API Manual, bestie ✨

Okay so picture this: you're out here comparing two ktime structures, right? And like... what if they overflow? 😭 That's literally the whole plot of this macro. It's the glow-up version of the standard ktime_compare() function — same energy, but it also attempts to handle ktime overflows. Not me being obsessed with a safety net, but here we are 🫶

---

✨ SYNOPSIS ✨

ktime_compare_safe (A , B );

That's it. Two little arguments and you're seated 💅

---

🎀 ARGUMENTS 🎀

• A — the first ktime value, aka the main character 👑
• B — the second ktime value, the costar of this little comparison 🦋

---

🔥 RETURN 🔥

The vibe check results are in, and there are exactly three outcomes:

• -1 if A < B
• 0 if A == B
• 1 if A > B

No in-between, no "it's complicated" — iconic behavior honestly 💀

Quick reminder bestie: this one attempts to also handle ktime overflows — that word "attempts" is doing a lot of work so like, don't @ me, just know what you're getting into 😌
