make_data_vio_pool(9)

okay bestie, welcome to make_data_vio_pool(9), fresh outta the Kernel API Manual 💖 we're gonna initialize a data_vio pool and it's gonna be iconic, no cap.

🌸 NAME 🌸

make_data_vio_pool — Initialize a data_vio pool. That's literally the whole name-section vibe: this is the pool-initializing call, periodt. ✨

💅 SYNOPSIS 💅

int make_data_vio_pool (struct vdo *vdo , data_vio_count_t pool_size ,
       data_vio_count_t discard_limit , struct data_vio_pool **pool_ptr );

🎀 ARGUMENTS 🎀

okay so the args are giving short but important, and here's every single one:

• vdo — the vdo to which the pool will belong. It's the main character this pool is attached to. 🫶
• pool_size — the number of data_vios in the pool. That's the headcount, bestie.
• discard_limit — the maximum number of data_vios which may be used for discards. Respect the limit 💅
• pool_ptr — a pointer to hold the newly allocated pool. It's the spot where the new pool gets held onto. ✨
