fc_fcp_timeout(9)

✨ NAME ✨

okay so bestie, welcome to fc_fcp_timeout(9) from the Kernel API Manual — this page is literally all about being the Handler for fcp_pkt timeouts 💅. That's the whole vibe: it's the timeout handler, periodt.

🌸 SYNOPSIS 🌸

void fc_fcp_timeout (struct timer_list *t );

🎀 ARGUMENTS 🎀

• t — the timer context, and yes it's used to fetch the FSP packet ✨.

🦋 DESCRIPTION 🦋

okay so here's the tea: if REC is supported then just issue it and return — no cap, that's the move. The REC exchange will complete or time out and recovery can continue at that point. The way that works is very “we'll let the REC do its thing and circle back” 😌.

Otherwise? If the response has been received without all the data, it has been ER_TIMEOUT since the response was received. If the response has not been received, we see if data was received recently. If it has been, then we continue waiting — literally just keep waiting, bestie. Otherwise, we abort the command. Boom. That's the whole decision tree, and it ate 🫶.
