scsi_block_requests(9)

💅 NAME 💅

okay so bestie, welcome to scsi_block_requests(9) from the Kernel API Manual ✨. This is scsi_block_requests — a utility function that low-level drivers use to prevent further commands from being queued to the device. That's the whole assignment, no cap 🎀.

🌸 SYNOPSIS 🌸

void scsi_block_requests (struct Scsi_Host *shost );

🦋 ARGUMENTS 🦋

• shost — the host in question, bestie 💖.

🔥 DESCRIPTION 🔥

okay so here's the tea ☕: there is no timer, and no other means by which the requests get unblocked, other than the low-level driver calling scsi_unblock_requests. Like... that's it. That's the whole escape route 💅.

⚠️ bestie, listen: this is not a "set it and forget it" vibe. No timer is gonna swoop in and save you. The low-level driver has to call scsi_unblock_requests. periodt 🫶.
