libeth_cache...truct_assert(9)

💅 libeth_cacheline_struct_assert(9) 💅

okay so welcome to the Kernel API Manual, bestie — this one is giving “make sure the CL-based struct size is expected,” and honestly? iconic.

✨ NAME ✨

libeth_cacheline_struct_assert — make sure CL-based struct size is expected. periodt.

🌸 SYNOPSIS 🌸

libeth_cacheline_struct_assert (type , ... );

🎀 ARGUMENTS 🎀

• type — type of the struct. like, the struct’s type, obviously 💅
• ... — from 1 to 3 CL group sizes (read-mostly, read-write, cold). feed it the group sizes, bestie 🫶

🦋 DESCRIPTION 🦋

When a struct contains several CL groups, it’s difficult to predict its size on different architectures. The macro instead takes sizes of all of the groups the structure contains and generates the final struct size. so yeah, no cap — it does the size math so you don’t have to guess across architectures. slay 🎀
