v4l2_fh_exit(9)

💅 v4l2_fh_exit(9) ✨ — your Kernel API Manual bestie 🫶

🌸 NAME 🌸

v4l2_fh_exit — releases resources related to a file handle. That's the whole assignment, bestie: file-handle cleanup, and it's giving iconic 💖.

✨ SYNOPSIS ✨

void v4l2_fh_exit (struct v4l2_fh *fh );

It returns void, so there's no return value to catch feelings over 😌.

🎀 ARGUMENTS 🎀

• fh — pointer to struct v4l2_fh 🫶. Literally the file-handle struct you're passing in.

🦋 DESCRIPTION 🦋

Okay so parts of the V4L2 framework that are using the v4l2_fh must release their resources here, too. Like, this is the spot where those resources get set free — no “I'll do it later” energy 💅.

💀 NOTE 💀

This must be called in the v4l2_file_operations->release handler if the driver uses struct v4l2_fh. Not optional, not a maybe, not a vibe — it's a must, bestie 🚨.
