get_slab_journal_statistics(9)

💅 get_slab_journal_statistics(9) 💅

okay so bestie, this page is from the Kernel API Manual, and it's literally about grabbing the aggregated slab journal stats for a depot. It's a tiny page but it's important, fr fr 🫶

---

💖 NAME 💖

get_slab_journal_statistics - get the aggregated slab journal statistics for the depot. Periodt ✨

---

✨ SYNOPSIS ✨

the signature is giving:

struct slab_journal_statistics get_slab_journal_statistics (const struct
slab_depot *depot );

---

🎀 ARGUMENTS 🎀

• depot — the slab depot. that's the whole argument, bestie 💅

---

🌸 RETURN 🌸

it returns the aggregated statistics for all slab journals in the depot. so you get the full lil summary of every slab journal in there, and that's iconic ✨
