💖 vdo_make_packer(9) 💖

okay bestie, we're in the Kernel API Manual and this page is literally about making a new block packer. no cap, I kept every single detail because we do not skip the important bits in this group chat 💅✨

🌸 NAME 🌸

vdo_make_packer — make a new block packer. that's the whole vibe: brand-new packer, fresh out the box 🎀

✨ SYNOPSIS ✨

here's the exact signature, bestie — keep it character-for-character, no edits, no "fixing" the spacing, periodt:

int vdo_make_packer (struct vdo *vdo , block_count_t bin_count , struct
       packer **packer_ptr );

🦋 ARGUMENTS 🦋

• vdo — the vdo to which this packer belongs. like, whose packer is this? that one 🫶
• bin_count — the number of partial bins to keep in memory. that's the count, bestie.
• packer_ptr — a pointer to hold the new packer. it's the spot where the new packer goes 💅

🌈 RETURN 🌈

it returns VDO_SUCCESS or an error. success or the error vibe, that's it 😭
