fc_fcp_can_queue_ramp_down(9)

📦 version 7.3.1, in nixpkgs unstable

💅 fc_fcp_can_queue_ramp_down — the Kernel API Manual one, bestie

okay so real talk, this is fc_fcp_can_queue_ramp_down(9) from the Kernel API Manual and she is, like, the chill-out function. The one that says "bestie, take a breath, we're doing too much." Let me tell you everything 💖

✨ NAME ✨

fc_fcp_can_queue_ramp_down — reduces can_queue 🫶

🌸 SYNOPSIS 🌸

bool fc_fcp_can_queue_ramp_down (struct fc_lport *lport );

🎀 ARGUMENTS 🎀

  • lport — the lport whose can_queue we're about to turn down. She's the one getting the vibe check 💅

🦋 DESCRIPTION 🦋

So here's the situation, and it's giving stress 😭 — if we're getting memory allocation failures, that's lowkey a sign we might be trying to execute too many commands at once. Like girl, pace yourself.

So what do we do? We let the running commands complete or timeout first (we don't just yank them, that would be rude), and then we try again with a reduced can_queue. Patient. Iconic. That's the move ✨

And eventually? We will hit the point where we run on all reserved structs. That's just where this road ends, no cap. 🫶

🔥 SEE ALSO 🔥

💀 reminder bestie: this is bool-returning, so check that return value, don't just vibe past it, iykyk.
