💅 megasas_stream_detect(9) — Kernel API Manual bestie edition 💅

okay so welcome to the Kernel API Manual corner of the group chat, where megasas_stream_detect(9) is the main character and we are obsessed. ✨ This page is short, sweet, and very much giving “driver internals but make it cute.” 🎀

💖 NAME 💖

stream detection on read and and write IOs — yes bestie, the double and is right there in the original flavor and we are not editing it. 💅 That’s the whole NAME tea: stream detection on read and and write IOs. 😭

✨ SYNOPSIS ✨

Copy-paste this exactly, no vibes-based edits:

void megasas_stream_detect (struct megasas_instance *instance , struct
megasas_cmd_fusion *cmd , struct IO_REQUEST_INFO *io_info );

the signature ate and left no crumbs — that’s the whole call, with the line break and the space before the comma preserved. 🫶

🫶 ARGUMENTS 🫶

• instance — Adapter soft state. That’s the adapter’s soft-state bestie, holding the context tea. 🦋
• cmd — Command to be prepared. This is the command getting ready for its moment. 💅
• io_info — IO Request info. The IO request’s info card, basically. 🎀
