fc_remove_host(9)

🦋 fc_remove_host(9) — Kernel API Manual 🦋

okay bestie, this is the Kernel API Manual page for fc_remove_host(9), and it's literally about cleaning up your fc_transport situation before things get cursed 💅

💖 NAME 💖

fc_remove_host — called to terminate any fc_transport-related elements for a scsi host. That's the whole vibe: break down the fc_transport stuff tied to a SCSI host ✨

✨ SYNOPSIS ✨

void fc_remove_host (struct Scsi_Host *shost );

🎀 ARGUMENTS 🎀

• shost — Which Scsi_Host 💖 (yep, that's the argument, and it tells the routine which host we're talking about)

🔥 DESCRIPTION 🔥

Okay so the expectation is that you call this routine immediately preceding the driver's call to scsi_remove_host — and yes, the original wording says “the a driver's call”, so we're preserving that little artifact, no cap 😭. Before, not after, not whenever.

⚠️ WARNING: A driver utilizing the fc_transport, which fails to call this routine prior to scsi_remove_host, will leave dangling objects in /sys/class/fc_remote_ports. Access to any of these objects can result in a system crash !!! This is not a drill, bestie 💀

🧚 NOTES 🧚

Lock vibe check: this routine assumes no locks are held on entry. None. Zero. Do not walk in holding a lock like it's a Starbucks cup 🔒🙅‍♀️
