tty_driver_kref_put(9)

💅 tty_driver_kref_put(9) 💅

okay bestie, welcome to the Kernel API Manual — today’s main character is tty_driver_kref_put(9), and it’s short, iconic, and to the point. 🎀✨

🎀 NAME 🎀

tty_driver_kref_put — drop a reference to a tty driver. that’s the whole name, slay 💅

✨ SYNOPSIS ✨

void tty_driver_kref_put (struct tty_driver *driver );

🌸 ARGUMENTS 🌸

• driver — the driver of which to drop the reference. literally the tty driver you’re letting go of, no cap 🫶

💖 DESCRIPTION 💖

The final put will destroy and free up the driver. so when the last reference goes bye-bye, the driver gets destroyed and freed — it’s giving last-one-out energy 😭💀

bestie, keep the “final” part in mind: this page says the final put is the one that destroys and frees up the driver. periodt.
