megasas_iss...ed_abort_cmd(9)

✨ NAME ✨

okay so this is the megasas_iss...ed_abort_cmd(9) page from the Kernel API Manual, and the function we're hyping up is megasas_issue_blocked_abort_cmd — it aborts a previously issued cmd. That's the whole main-character job. 💅

🦋 SYNOPSIS 🦋

Here's the signature, copied exactly because we do not mess with code in this house:

int megasas_issue_blocked_abort_cmd (struct megasas_instance *instance ,
struct megasas_cmd *cmd_to_abort , int timeout );

🎀 ARGUMENTS 🎀

• instance — the adapter soft state, aka the adapter's whole vibe.
• cmd_to_abort — the previously issued cmd that's getting aborted. Bye bestie. 👋
• timeout — timeout in seconds. Tick tock. ⏳

🌸 DESCRIPTION 🌸

so here's the tea: MFI firmware can abort a previously issued AEN comamnd (automatic event notification). Yes, comamnd — that's how it's written here, and honestly? Iconic. 💀

megasas_issue_blocked_abort_cmd issues such an abort cmd and then waits for return status. It's giving "I sent the abort, now I'm waiting by the phone." 😭

⏳ Max wait time is MEGASAS_INTERNAL_CMD_WAIT_TIME secs. That's the cap, bestie — no infinite waiting era.
