💅 mmc_release_host(9) — from the Kernel API Manual, bestie

okay so this is a page out of the Kernel API Manual and it's literally the "let go of the host" girlie. sit down, we're learning ✨

🎀 NAME

mmc_release_host — release a host. that's it, that's the whole vibe. she lets go 💖

---

🌸 SYNOPSIS

void mmc_release_host (struct mmc_host *host );

returns nothing (void, so no take-backsies), takes one pointer, and it's go time 🦋

---

🧚 ARGUMENTS

• host — the mmc host you're releasing. hand her over, bestie 🫶

---

✨ DESCRIPTION

so basically: you release a MMC host, which lets other people claim the host for their own operations. it's giving "sharing is caring", it's giving "the host is communal property and you were just borrowing her" 👑 no gatekeeping, no cap 💅

like if you're holding the host and someone else needs her for their operations — boom, mmc_release_host and she's available. main character energy for everyone 🌈
