qla4xxx_eh_host_reset(9)

okay bestie, welcome to qla4xxx_eh_host_reset(9) from the Kernel API Manual — it's giving kernel callback and we're reading it together, no cap. 💅

🌸 NAME 🌸

qla4xxx_eh_host_reset — kernel callback. That's the name, periodt. ✨

🦋 SYNOPSIS 🦋

the signature is literally this, copy it exactly:

int qla4xxx_eh_host_reset (struct scsi_cmnd *cmd );

🎀 ARGUMENTS 🎀

• cmd — a pointer to Linux's SCSI command structure. That's the whole argument list, bestie: one pointer and done. 🫶

💖 DESCRIPTION 💖

This routine is invoked by the Linux kernel to perform fatal error recovery on the specified adapter. So yeah — when the kernel has to do fatal error recovery on that adapter, this is the callback that gets called. It's lowkey the emergency-response main character of this page. 🔥
