✨ set_data_vi...ssion_status(9) ✨

okay bestie, welcome to this Kernel API Manual page, section 9 energy. The main character here is set_data_vi...ssion_status(9), and the function it's hyping is set_data_vio_compression_status — it's literally about setting the compression status of a data_vio. no cap 💅

💖 NAME 💖

set_data_vio_compression_status — Set the compression status of a data_vio. that's the whole name vibe 🎀

📜 SYNOPSIS 📜

bool set_data_vio_compression_status (struct data_vio *data_vio , struct data_vio_compression_status status , struct data_vio_compression_status new_status );

the way this signature is giving “three things go in, one bool comes out” ✨

🧚 ARGUMENTS 🧚

• data_vio — The data_vio to change. glow-up target.
• status — The expected current status of the data_vio.
• new_status — The status to set.

🌈 RETURN 🌈

Returns true if the new status was set. Returns false if the data_vio's compression status did not match the expected state, and so was left unchanged. match check said no, so it stays exactly where it was 😭 periodt.
