requires_reaping(9)

💖 NAME — requires_reaping(9) 💖

okay so welcome to the Kernel API Manual, bestie. This page is for requires_reaping(9), and its whole thing is: check whether the journal must be reaped before adding new entries. That’s it. That’s the assignment. ✨

🌸 SYNOPSIS 🌸

bool requires_reaping (const struct slab_journal *journal );

It’s giving “tiny function, big bool energy.” 💅

🎀 ARGUMENTS 🎀

• journal — the journal to check. That’s the one and only argument, bestie. 🫶

⭐ RETURN ⭐

True if the journal must be reaped. So if it hits you with True, that journal is lowkey telling you it needs reaping before new entries get added, and you gotta respect it. periodt. 💀
