irq_exit(9)

🎀 NAME 🎀

okay so this is the irq_exit(9) page from the Kernel API Manual, and the NAME line is literally irq_exit - Exit an interrupt context, update RCU and lockdep. that's the whole vibe: exit an interrupt context, update RCU and lockdep, and (per the description) also process softirqs if needed and possible 💅✨

🦋 SYNOPSIS 🦋

here's the signature, bestie, exactly as it appears:

void irq_exit (void );

🌸 ARGUMENTS 🌸

• void — no arguments. zero, zilch, none, bestie — the argument section is literally void with no arguments, and that's iconic 🫶

🔥 DESCRIPTION 🔥

so you're exiting an interrupt context and updating RCU and lockdep (that's straight from the NAME line), and the extra little garnish is this exact sentence: Also processes softirqs if needed and possible. if it's needed and if it's possible, it processes those softirqs; that's the whole description, no cap 💖
