cache_cohere...stance_alloc(9)

💅 cache_cohere...stance_alloc(9) 💅

ok so this is a page from the Kernel API Manual, bestie — the manpage name got truncated all cute like cache_cohere...stance_alloc(9) but it's really all about cache_coherency_ops_instance_alloc ✨

---

🎀 NAME 🎀

cache_coherency_ops_instance_alloc — allocates a cache coherency ops instance 🫶

---

🌸 SYNOPSIS 🌸

cache_coherency_ops_instance_alloc (ops , drv_struct , member );

like literally that's the whole call, yes the spacing is a little feral, that's just how it is 💀

---

🦋 ARGUMENTS 🦋

• ops — the cache maintenance operations, aka the actual ops you're bringing to the party 🎀
• drv_struct — the structure that contains the struct cache_coherency_ops_inst, iykyk 👑
• member — the name of the struct cache_coherency_ops_inst member inside drv_struct, like which drawer the thing lives in 🗄️ ✨

---

💖 DESCRIPTION 💖

okay so what this does: it allocates a driver specific structure and then initializes the cache_coherency_ops_inst that's embedded in the drv_struct 🌈 literally just sets your instance up so it's ready to go, main character energy fr fr.

⚠️ bestie listen — upon success the pointer must be freed via cache_coherency_ops_instance_put. don't just leave it there, that's not slay, that's a leak 🙈

Returns a drv_struct * on success, NULL on error 💅 so like, check it before you use it, obviously.

🔥 SEE ALSO 🔥

• Kernel file ./include/linux/cache_coherency.h — go read it, it ate ⭐

and that's the whole vibe check bestie 🧚💜 this one's from the ./include/linux gang, dated October 2026 — the manual page header even says cache_cohere...stance_alloc(9) on both ends because consistency is iconic 😭💖 go forth and allocate responsibly 🍓
