okay so bestie, this is a page straight outta the Kernel API Manual — and it's here to answer one very specific question: is this bo suitable for shinking? (yes, “shinking” is the spelling on the page, not me 😭). Anyway, slay, let's get into it.

🔮 SYNOPSIS 🔮

bool ttm_bo_shrink_suitable (struct ttm_buffer_object *bo , struct
       ttm_operation_ctx *ctx );

🧸 ARGUMENTS 🧸

• bo — the candidate for shrinking. this is the little guy under consideration 💅
• ctx — the struct ttm_operation_ctx governing the shrinking.

🌸 DESCRIPTION 🌸
