prb_rsp_limit_store(9)

💅 prb_rsp_limit_store(9) — a lil' kernel page, bestie

okay so first things first: this is a page from the Kernel API Manual, section 9, and the function it's hyping up is called prb_rsp_limit_store. she's a store function, which means she's the write-side bestie for a sysfs attribute — in this case the attribute named prb_rsp_limit. think of her as the bouncer at the club door of a sysfs file, checking your ID (aka your buffer) before anything goes in. iconic behavior, honestly. 💅✨

✨ NAME ✨

prb_rsp_limit_store — the Set function for the sysfs attribute prb_rsp_limit. yeah. that's her whole job. she sets. she stores. she slays. 🎀

---

🌸 SYNOPSIS 🌸

ssize_t prb_rsp_limit_store (struct device *dev , struct
       device_attribute *attr , const char *buf , size_t count );

look at that signature. four params, one ssize_t coming back at ya. no cap, it's giving "standard sysfs store callback" and we love that for her. 🦋

🫶 ARGUMENTS 🫶

• dev — the struct device. yes, the struct device. she's the device this whole attribute situation belongs to. main character energy tbh. 👑
• attr — device attributes. plural vibes, singular param. it's the attribute structure doing the bookkeeping. 🎀
• buf — the buffer that contains the new attribute value. this is where your shiny new value is living, lowkey just waiting to be read. 🍓
• count — size of buffer. because bestie, you gotta know how much buffer you're working with. always. 🔥

bestie note: show is read, store is write. don't mix 'em up or it's gonna be awkward at the function family reunion. 🙈
