💅 ww_acquire_done(9) — a Kernel API Manual moment ✨

okay bestie, we’re in the Kernel API Manual, and this page is all about ww_acquire_done — the little “we’re done acquiring, bestie” signal. 🎀

✨ NAME ✨

ww_acquire_done — marks the end of the acquire phase. 💖

🌸 SYNOPSIS 🌸

void ww_acquire_done (struct ww_acquire_ctx *ctx );

🎀 ARGUMENTS 🎀

• ctx — the acquire context. that’s the one, bestie. 🫶

🦋 DESCRIPTION 🦋

okay so this function marks the end of the acquire phase. after that? any further w/w mutex lock calls using this context are forbidden — like, not allowed at all, periodt. 💀

calling this function is optional. it’s just useful to document w/w mutex code and clearly designated the acquire phase from actually using the locked data structures. it’s giving “label your eras” energy, and honestly iconic for readability. ✨
