t3_reset_qset(9)

💖 t3_reset_qset(9) — a Kernel API Manual bestie moment

okay so welcome to the t3_reset_qset(9) page from the Kernel API Manual. this is your group-chat briefing on resetting a sge qset, and yes, we’re keeping every single detail because that’s the whole vibe. ✨

🎀 NAME

t3_reset_qset — reset a sge qset. that’s the assignment, bestie, and it ate. 💅

✨ SYNOPSIS

void t3_reset_qset (struct sge_qset *q );

🎀 ARGUMENTS

• q — the queue set. literally the queue set. no extra lore, no plot twist.

🦋 DESCRIPTION

So you’re resetting the qset structure. the NAPI structure is preserved in the event of the qset’s reincarnation — for example during EEH recovery. that’s the important part: reset the qset structure, but the NAPI structure stays preserved when the qset comes back around. iconic behavior, honestly. 💖
