svc_stat_alloc_counts(9)

💅 svc_stat_alloc_counts(9) — the Kernel API Manual, bestie edition 🎀

ok so like. first of all, welcome to the Kernel API Manual ✨ (yes, that manual, the kernel one, we're doing this). today's main character is svc_stat_alloc_counts, and honestly? she's a little allocator with one job and she does it. no cap.

---

🌸 NAME 🌸

svc_stat_alloc_counts — allocate per-netns per-version call count arrays 💖

like. it allocates. the count arrays. per netns AND per version. both. at once. she's efficient like that 🫶

---

⭐ SYNOPSIS ⭐

int svc_stat_alloc_counts (struct svc_stat *statp );

literally just one argument, one return, we love a minimal signature 👑

---

🦋 ARGUMENTS 🦋

• statp — the svc_stat whose vs_count arrays should be allocated. that's her whole thing. that's the assignment. the vs_count arrays are getting allocated and statp is the girlboss it's happening for 💅

---

🔥 DESCRIPTION 🔥

okay so here's the tea ☕: statp->program must be set before calling this. like, before. not during, not after, not "oops I'll set it in a minute". before. consider this your vibe check 🚨

returns zero on success 🎉, or a negative errno otherwise 😭 (yes, plural errnos, it can hand you any one of the negative ones, don't ask which, the page isn't telling, and neither am I, because I refuse to make up lore).

fr fr set statp->program first. that's not a suggestion, that's the prerequisite. periodt. 💀
