iscsi_unblock_session(9)

✨ iscsi_unblock_session — the "you're SO back" moment for a session ✨

okay so bestie, this one lives in the Kernel API Manual, and the function is iscsi_unblock_session(9). It's literally the glow-up arc: a session that was blocked gets its main character moment and starts doing IO again 💅

🌸 SYNOPSIS 🌸

void iscsi_unblock_session (struct iscsi_cls_session *session );

🎀 ARGUMENTS 🎀

• session — the iscsi session in question 🦋 (yes, that's the whole arg, she's low maintenance)

💖 DESCRIPTION 💖

So what does it actually do? Mark a session as ready to accept IO. That's it. That's the whole vibe 💫

Like — you flip the session back into "yes queen, take the IO" mode. No cap.

ngl the manpage is short here, so I'm not gonna invent lore: it marks the session as ready to accept IO, periodt 🔥
