💅 drm_event_cancel_free(9)

okay so bestie, welcome to the Kernel API Manual ✨ this one's short and sweet — it's the cleanup crew of the DRM event world, and honestly it deserves its flowers 🎀

🌸 NAME 🌸

drm_event_cancel_free — frees a DRM event and releases its space 🫶

✨ SYNOPSIS ✨

void drm_event_cancel_free (struct drm_device *dev , struct
drm_pending_event *p );

that's it. two args, zero return value, all vibes 💅

🦋 ARGUMENTS 🦋

  • dev — the DRM device 👑
  • p — the tracking structure for the pending event, aka the little guy holding down the fort while the event waits its turn 🥺

💖 DESCRIPTION 💖

So here's the tea ☕: this function frees the event p — the very same one you initialized with drm_event_reserve_init — and releases any space that got allocated along the way. Literally cleans up everything, no crumbs left behind 🧹✨

It's the emergency exit 🚪 you call when a nonblocking operation could not be submitted and needed to be aborted. Like, the mission got cancelled, but the reserved memory doesn't get to just hang around being extra. Not on this function's watch 💀

lowkey iconic of it to take the fall so your kernel doesn't leak memory. main character energy fr fr 🔥
