pmcraid_error_handler(9)

💖 NAME 💖

Okay bestie, this is pmcraid_error_handler(9) from the Kernel API Manual — manual name folded in right at the top like a cute little name tag. It's giving “error response handlers for a SCSI op,” and we are so here for it. ✨

📜 SYNOPSIS 📜

int pmcraid_error_handler (struct pmcraid_cmd *cmd );

🎀 ARGUMENTS 🎀

• cmd — a pointer to the pmcraid_cmd that has failed, literally the whole reason we're here. 💅

🌸 DESCRIPTION 🌸

So here's the vibe: this function determines whether or not to initiate ERP on the affected device. No cap, that's the decision it's making.

It's called from a tasklet, and that tasklet doesn't hold any locks — important detail, bestie. 🔒❌

Return value check, because yes: 0 means the caller can complete the request; otherwise 1, where the error handler itself completes the request and returns the command block back to the free-pool. Periodt. 🫶
