✨ release_com...write_waiter(9) ✨

okay bestie, welcome to the Kernel API Manual, where today's main character is release_com...write_waiter(9) — yes, the title is truncated like that, but the actual function is release_compressed_write_waiter. the way this name ate, honestly 🎀

🌸 NAME 🌸

release_compressed_write_waiter — update a data_vio for which a successful compressed write has completed, and send it on its way. that's the whole assignment, and it's giving "finish line, but make it kernel" 💅

🦋 SYNOPSIS 🦋

void release_compressed_write_waiter (struct data_vio *data_vio , struct
       allocation *allocation );

it returns void, so no return-value drama here, fr fr 🫶

🎀 ARGUMENTS 🎀

• data_vio — the data_vio to release. that's the little guy getting sent off 😭
• allocation — the allocation to which the compressed block was written. literally the destination tea ☕
