vb2_destroy_framevec(9)

💅 NAME 💅

vb2_destroy_framevec — okay so this one releases a whole vector of mapped pfns, bestie ✨

🌸 SYNOPSIS 🌸

void vb2_destroy_framevec (struct frame_vector *vec );

🎀 ARGUMENTS 🎀

• vec — the vector of pfns / pages that you're about to set free 🦋 literally handing it its walking papers.

✨ DESCRIPTION ✨

So here's the vibe: this function drops all the references to every page in the vector vec — but only if the corresponding pfns are actually backed by pages, iykyk 🙈 — and then it frees the vector you passed in. Two-for-one slay 💅

Fr fr, it's the cleanup bestie. It lets go of the pages and yeets the vector itself. Don't touch vec after this, no cap 💀
