arch_irqent...need_resched(9)

okay so bestie, welcome to the arch_irqent...need_resched(9) page from the Kernel API Manual ✨ this one is short, sweet, and extremely architecture-coded 🫶

💖 NAME 💖

arch_irqentry_exit_need_resched — the architecture-specific need-resched function. that's the whole name, no cap 💅

✨ SYNOPSIS ✨

bool arch_irqentry_exit_need_resched (void );

🎀 ARGUMENTS 🎀

• void — no arguments. literally none, bestie. the void ate and left no crumbs 🍓

🦋 DESCRIPTION 🦋

so this function gets invoked from raw_irqentry_exit_cond_resched to check if resched is needed. defaults return true — iconic default behavior, honestly 💖

the main purpose? it's to permit arch to avoid preemption of a task from an IRQ. yes, that's the whole vibe: arch gets to dodge preempting a task from an IRQ when it needs to 🌸
