store_release_wake_up(9)

✨ NAME ✨

Okay so store_release_wake_up(9) — yes, from the Kernel API Manual — is literally here to update a variable and send a wake_up, periodt. It's giving "change the value, then wake the waiters" energy. 💅

🌸 SYNOPSIS 🌸

store_release_wake_up (var , val );

🦋 ARGUMENTS 🦋

• var — the address of the variable to be updated and woken. Yes bestie, the address, not the vibe.
• val — the value to store in the variable.

💖 DESCRIPTION 💖

Store the given value in the variable and send a wake up to any tasks waiting on the variable. All the necessary barriers are included to ensure the task calling wait_var_event sees the new value and all values written to memory before this call. That's the whole slay: barriers are doing their thing so the caller sees the fresh value and everything written before this call. ✨
