zfcp_dbf_rec_trig_lock(9)

📦 version 7.3.1, in nixpkgs unstable

💅 NAME 💅

zfcp_dbf_rec_trig_lock — bestie, this is the one that traces a triggered recovery with the lock situation, and honestly it's giving "tiny function, big responsibility" ✨

(also hi, you're reading the zfcp_dbf_rec_trig_lock(9) page from the Kernel API Manual 🎀)

🌸 SYNOPSIS 🌸

void zfcp_dbf_rec_trig_lock (char *tag , struct zfcp_adapter *adapter ,
struct zfcp_port *port , struct scsi_device *sdev , u8 want , u8 need );

no cap, that's the whole signature — six args, one void, zero drama 🦋

✨ ARGUMENTS ✨

okay so here's who's who in the group chat:

  • tag — the identifier for the event 🏷️ like a little name badge so you know which trace you're looking at
  • adapter — the adapter on which the erp_action should run 👑
  • port — the remote port that's involved in the erp_action 🌈
  • sdev — the scsi device involved in the erp_action 💖
  • want — the wanted erp_action 🫶 (what we're hoping for)
  • need — the required erp_action 🔥 (what we actually gotta have)

💀 DESCRIPTION 💀

real talk, the important bit is this one line:

adapter->erp_lock must not be held. 🚨

like, do not be holding that lock, bestie. it's not the vibe. the function says so, I say so, periodt 💅
