arm_smmu_invs_for_each_cmp(9)

💅 NAME 💅

Hii bestie, welcome to the Kernel API Manual page for arm_smmu_invs_for_each_cmp — yes, that whole name, no cap. This helper is literally here to iterate over two sorted arrays and compute stuff for arm_smmu_invs_merge() or arm_smmu_invs_unref(). It’s giving “tiny helper with main character energy,” and we’re obsessed. 🦋

✨ SYNOPSIS ✨

arm_smmu_invs_for_each_cmp (invs_l , idx_l , invs_r , idx_r , cmp );

🎀 ARGUMENTS 🎀

• invs_l — the base invalidation array. Your left-side main character. 👑
• idx_l — a stack variable of size_t, to store the base array index. Bestie, it’s a stack variable, so keep it cozy. 🫶
• invs_r — the build_invs array as to_merge or to_unref. Basically the right-side array with a job. 💅
• idx_r — a stack variable of size_t, to store the build_invs index. Another stack cutie, another index. ✨
• cmp — a stack variable of int, to store the return value, which is -1, 0, or 1. That’s the vibe check result, periodt. 🔥
